Can I add row spacers to my existing pallet racks?

Yes. Our bolt-on row spacers can be installed on most existing back-to-back pallet rack systems without major disassembly or modification, including teardrop pallet racks, keystone racks, and structural rack systems. Installation requires only basic hand tools — the row spacer bolts directly to the upright frame columns of both back-to-back rows at the specified height. To retrofit row spacers on a loaded rack, the beam levels at the spacer installation height can remain loaded while the spacers are attached to the upright column sections below or between beam levels. For seismic zone retrofits, a qualified engineer should specify spacer location, quantity, and bolt torque requirements based on rack height, column load, and local building code. Contact Pallet Storage Solutions at 734-621-5052 to verify spacer compatibility with your existing upright column profile before ordering.

Q: What is a row spacer used for in pallet racking?

A pallet rack row spacer is a steel connector that bolts between the upright frames of two back-to-back rack rows, maintaining a fixed, consistent gap between them. Row spacers serve three structural functions: (1) Load distribution — they transfer lateral forces (forklift impact, seismic loads, eccentric loading) from one rack row to the adjacent row, effectively doubling the lateral resistance of the combined structure; (2) Geometric stability — they prevent rack rows from 'walking' apart or together over time from repeated forklift loading cycles, maintaining consistent aisle widths and preventing aisle width violations that create forklift clearance hazards; (3) Redundant load paths — in the event of upright damage to one row, the row spacer provides an alternative load path to the adjacent undamaged row, helping contain damage and prevent progressive collapse. Row spacers are required by ANSI MH16.1 for all back-to-back rack configurations and are recommended by OSHA for stable rack structures. Contact Pallet Storage Solutions at 734-621-5052 for row spacer selection guidance.

Q: What lengths are available for row spacers?

Pallet Storage Solutions offers row spacers in standard lengths of 6, 8, 12, 18, and 24 inches, plus custom lengths for non-standard back-to-back row spacing configurations. The correct row spacer length equals the required back-to-back gap between the two rack row upright frames — determined by the rack system's engineering drawings, seismic zone requirements, or fire code minimum clearance specifications. Seismic zone installations typically require a minimum 4-inch gap between back-to-back rows per local building codes. Fire code may require a minimum 6-inch flue space between back-to-back rows for sprinkler system effectiveness. For seismic and special application row spacers, contact Pallet Storage Solutions at 734-621-5052 for the correct spacer length based on your rack configuration and local code requirements.

Q: Do I need row spacers on every back-to-back rack?

Yes. Row spacers are essential for all back-to-back pallet racking configurations and are not required for single-row wall-mounted racks. ANSI MH16.1 requires row spacers on all back-to-back selective rack installations. The minimum installation requirement is two row spacers per upright frame — one near the top beam level and one near the middle — with additional spacers recommended for taller racks (above 20 feet) and seismic zone installations. The recommended installation interval is every 5 to 6 feet of upright height. Seismic zone installations may require closer spacing per local building code. Operating back-to-back racks without row spacers is an OSHA violation — racks without spacers are not anchored to each other and can progressively separate or collapse under lateral loading. Contact Pallet Storage Solutions at 734-621-5052 for a row spacer quantity recommendation for your specific rack configuration.

Q: How many row spacers should I use per rack section?

The minimum is two row spacers per upright frame pair — one installed near the top beam level and one near the middle of the upright height. For racks taller than 15 feet, three spacers per frame are recommended: top, middle, and lower third. For racks in seismic zones, local building codes typically specify minimum spacer quantity and location — consult your structural engineer or local building official for seismic zone requirements. The recommended installation interval regardless of rack height is every 5 to 6 feet of vertical height. For back-to-back rack rows with multiple column bays, spacers should be installed at every upright frame pair — not just at row ends. Contact Pallet Storage Solutions at 734-621-5052 for a spacer quantity recommendation based on your specific upright height and bay configuration.

Standard lengths 6", 8", 12", 18", and 24" — custom lengths available. Bolt-on installation, no major disassembly required. OSHA and ANSI MH16.1 compliant. Ships nationwide from Monroe, MI.

Features & Benefits

Key advantages that make our row spacers the ideal choice for optimizing pallet racking stability and OSHA compliance in demanding warehouse environments.

Heavy-Duty Construction

Premium structural steel — engineered to transfer lateral forces between back-to-back rack rows without deformation under repeated forklift loading cycles.

Improved Rack Stability

Maintains precise back-to-back spacing to prevent rack rows from shifting, "walking" apart, or collapsing from lateral loads or forklift impact forces.

Enhanced Warehouse Safety

ANSI MH16.1 requires row spacers on all back-to-back rack installations. Reduces accident risk from rack misalignment and provides redundant load paths that contain progressive collapse.

Universal Compatibility

Bolt-on design fits most standard rack systems — teardrop, keystone, and structural. Retrofittable to loaded existing racks without major disassembly. Verify upright column profile before ordering.

Quick Installation

Bolt-on design requires only basic hand tools — installs on existing loaded racks at upright column sections between or below beam levels without disrupting operations.

Multiple Lengths & Types

Standard lengths 6", 8", 12", 18", and 24". Standard, heavy-duty, adjustable, and seismic types available. Custom lengths for non-standard row spacing or fire code flue space requirements.

ANSI MH16.1 Required

ANSI MH16.1 mandates row spacers on all back-to-back selective rack installations. Non-compliance is an OSHA violation — all back-to-back racks must be retrofitted with row spacers before use.

Corrosion-Resistant Finish

Powder-coated finish for indoor warehouse environments. Hot-dip galvanized option available for cold storage, outdoor, and high-humidity facilities where moisture causes long-term steel corrosion.

Prevents Aisle Narrowing

Row spacers lock back-to-back rows at the correct OSHA-required aisle width — preventing the gradual aisle narrowing that creates forklift clearance violations and increases collision risk over time.

Types of Row Spacers

Four row spacer types tailored to diverse warehouse requirements — from standard selective rack installations to seismic zone compliance.

Standard Row Spacers

Ideal for typical warehouse applications with selective pallet racking in standard environments. Most commonly used for back-to-back selective and double-deep rack installations.

Best For: Standard selective pallet racking
Features: Reliable performance, moderate load capacity

Heavy-Duty Row Spacers

Reinforced construction for high-capacity or cold storage environments with heavier pallet loads and galvanized finish for moisture resistance in refrigerated facilities.

Best For: High-capacity storage, cold storage
Features: Reinforced construction, high load ratings

Adjustable Row Spacers

Telescoping multi-position design for warehouses with changing layouts or aisle widths — adjustable without removing from the installed position on the upright column.

Best For: Dynamic warehouse layouts
Features: Telescoping, multi-position design

Seismic Row Spacers

Enhanced lateral load resistance for earthquake-prone regions — California, Pacific Northwest, and New Madrid Seismic Zone. Engineered to meet local building code seismic specifications.

Best For: High-seismic zones
Features: Enhanced lateral load resistance

How Row Spacers Work

Three structural mechanisms by which row spacers integrate into back-to-back racking to prevent hazards and provide structural integrity.

Load Distribution

Transfers lateral forces (forklift impact, seismic) from one rack row to the adjacent row, effectively doubling the lateral resistance of the combined back-to-back structure.

Geometric Stability

Prevents rack "walking" — the gradual separation or convergence of back-to-back rows over time from repeated forklift loading — maintaining precise aisle widths and forklift clearance.

Redundant Support

Provides alternative load paths through the adjacent undamaged row if one row column sustains forklift impact — helping contain damage and prevent progressive collapse of the system.

Pro Tip: Install row spacers at multiple heights for comprehensive stabilization — minimum two per upright frame (near top and middle), with additional spacers every 5–6 feet for taller racks. Seismic zones may require closer spacing per local building code.

Applications & Use Cases

Row spacers deliver unmatched versatility across a wide range of warehouse environments where back-to-back pallet racking is used.

Distribution Centers

Manages large back-to-back rack systems with high forklift traffic — standard row spacers maintain aisle dimensions and contain progressive damage from repeated minor impacts.

Cold Storage

Heavy-duty galvanized row spacers maintain back-to-back alignment for safe pallet movement in refrigerated and frozen environments where corrosion resistance is critical.

Manufacturing

Supports heavy raw material and finished goods storage on back-to-back racks near assembly lines — heavy-duty row spacers handle the increased lateral loads from heavier pallet weights.

E-commerce & Retail

Optimizes high-density back-to-back inventory storage in e-commerce fulfillment centers with fast pick rates and frequent forklift activity at all hours.

Automotive & Industrial

Handles bulky or irregular loads on back-to-back cantilever or structural racking in automotive parts and industrial supply warehouses.

Pharmaceutical & Healthcare

Maintains precise back-to-back row alignment in pharmaceutical and healthcare warehouses where rack stability directly impacts inventory integrity and regulatory compliance.

Third-Party Logistics (3PL)

3PL facilities handling diverse client inventory types depend on precise back-to-back aisle widths for multi-client forklift operations — row spacers maintain consistent aisle geometry regardless of load changes.

High-Bay Warehouses

Tall back-to-back rack systems (above 20 ft) experience greater lateral sway forces — seismic and heavy-duty row spacers installed at 5-ft intervals provide the additional bracing these high-bay configurations require.

Compatibility & Installation Guide

Our row spacers integrate with selective pallet racks, drive-in racks, push-back racking, and other systems — straightforward bolt-on installation with basic hand tools.

1. Align Frames

Position two back-to-back upright frames at the correct gap distance specified by the rack engineering drawings, seismic code, or fire code flue space requirement.

2. Position Spacers

Place spacers at recommended intervals (every 5–6 feet of upright height). Minimum two per upright frame — one near top beam, one near middle. Seismic zones may require closer spacing.

3. Attach Spacers

Bolt row spacer to both upright columns with provided hardware. Tighten to specified torque — under-torqued bolts allow spacer movement that defeats the lateral transfer function.

4. Verify & Tighten

Verify even spacing at all spacer locations with a tape measure. Confirm all bolts are fully tightened. Install OSHA-required load capacity placards before returning rack to service.

Pro Tip: Install at least two spacers per frame — one near the top and one near the middle — for maximum stability. For seismic zone installations, consult a qualified engineer for spacer location and bolt torque specifications before installation.

Maintenance & Inspection Tips

OSHA requires annual inspection of all rack components — proactive row spacer maintenance ensures they remain effective and keeps your facility in compliance.

Annual OSHA Inspections

OSHA requires annual rack inspections. Include row spacer condition in your inspection — check for corrosion, deformation, and loose bolts. Document findings in your written inspection report.

Tighten Connections

Check bolt torque every six months in high-traffic facilities. Vibration from forklift operations can loosen fasteners over time — retighten to specified torque when any loosening is found.

Clean Periodically

Remove dust, debris, and product residue from spacer connection points. In food, pharmaceutical, and cold storage environments, clean with approved sanitizing solutions per facility protocols.

Replace Damaged Parts

OSHA requires immediate replacement of bent, cracked, or heavily corroded row spacers — damaged spacers cannot transfer lateral loads and must not remain in service. Replace only with rated components.

Verify Rack Alignment

Measure back-to-back row spacing at each spacer location annually. Spacing outside the specified tolerance indicates spacer loosening or rack movement — investigate and correct before next use.

Schedule Professional Inspections

OSHA requires annual rack inspections by a qualified person with a written report. Pallet Storage Solutions provides certified rack inspection services — call 734-621-5052 to schedule.

Touch Up Protective Coatings

For outdoor and cold storage spacers, inspect galvanized coating annually for bare spots. Touch up powder-coated spacers with compatible paint at scratches to prevent rust from spreading.

Document All Findings

OSHA requires written rack inspection reports — document spacer condition, bolt torque checks, and replaced components. Maintain records for a minimum of three years for compliance audit purposes.

Pro Tip: Combine row spacers with other pallet rack accessories such as column protectors and post protectors for a complete warehouse safety system. Pallet Storage Solutions provides certified annual rack inspection services — call 734-621-5052.

Compliance & Standards

Row spacers are rigorously tested and certified to meet the highest industry benchmarks for warehouse safety and structural performance.

OSHA 29 CFR 1910.176

OSHA requires all pallet rack systems to be maintained in safe condition with secure structural components. Back-to-back racks without row spacers violate the structural stability requirement — all installed spacers must be free of damage and bolts must be properly torqued.

ANSI MH16.1

ANSI MH16.1 (the RMI standard for industrial steel storage racks) requires row spacers on all back-to-back selective rack installations and specifies minimum spacer quantity and placement. Seismic zone installations require additional spacer specifications per local building code.
