| Wire Decking | Creates a stable, ventilated surface across rack beams. | Common widths: 42–48 in Common depths: 42–48 in Capacity: often 2,000–5,000 lb per level, depending on the product and support span | Prevents loose cartons from falling through beams and improves visibility, air circulation, and light penetration. | Cartons, totes, boxed inventory, and palletized goods | Beam lengthFrame depthUniform loadFire-sprinkler clearance |
| Pallet Supports | Supports pallets between front and rear beams when additional stability is needed. | Typical profile: steel channel or bar Common use: two or more supports per pallet position, based on pallet design and load | Reduces pallet deflection and helps keep damaged or non-standard pallets from slipping between beams. | Wooden pallets, plastic pallets, and irregular pallet loads | Pallet typeBeam spacingSupport countLoad distribution |
| Backstop Beams | Limits the rearward movement of pallets and protects the rack or wall behind the load. | Placement: installed behind pallet positions Design: must be sized and positioned to avoid contact with pallet loads | Maintains consistent pallet placement and reduces the risk of loads being pushed too far into the rack. | Deep loads, high-turnover pallet storage, and racks near walls | Load depthClearanceRack configurationImpact protection |
| Row Spacers | Maintains a controlled gap between back-to-back rack rows. | Spacing: determined by building layout, seismic requirements, and equipment clearance | Keeps rack rows aligned, protects stored goods, and helps preserve access for inspection and maintenance. | Back-to-back pallet racks in high-density layouts | Aisle planBuilding movementRack heightLocal code |
| Column Protectors | Absorbs or deflects impact from forklifts and other material-handling equipment. | Common heights: 12–48 in Types: steel, polymer, bolt-on, or floor-mounted designs | Reduces damage to upright frames and helps maintain rack stability in busy operating areas. | Rack uprights near aisles, doors, and vehicle routes | Impact levelClearanceMounting methodVisibility |
| Safety Back Mesh | Acts as a barrier to help prevent items from falling from the rear of a rack. | Common panel heights: 3–8 ft Mesh opening: selected according to the size of stored items and risk assessment | Improves worker protection and keeps loose cartons or components contained within the rack footprint. | Small cartons, containers, and storage areas beside walkways | Item sizeFall riskRack heightAccess requirements |
| Carton Flow Decks | Uses rollers or wheels to move cartons from the replenishment side toward the picking side. | Typical load: about 50–250 lb per carton lane, depending on the deck design Stock rotation: supports FIFO workflows | Separates replenishment from picking and reduces walking, reaching, and manual searching. | Cartons, totes, cases, and date-sensitive inventory | Carton weightCarton baseLane depthFIFO need |
| Pallet Flow Rails | Uses gravity rollers to move pallets through a lane from loading to unloading. | Lane depth: commonly several pallet positions Operating principle: FIFO flow with controlled speed | Improves stock rotation, reduces forklift travel inside the lane, and increases accessible pallet density. | Perishable goods, batch-controlled inventory, and high-volume operations | Pallet qualityLane depthLoad weightBrake rollers |
| Shelf Panels | Creates adjustable storage levels for hand-loaded products. | Common shelf depth: 12–24 in Capacity: often 200–1,000 lb per level, depending on panel type and span | Divides vertical space into organized picking locations and reduces floor-level clutter. | Small parts, cartons, tools, files, and maintenance supplies | Item weightShelf spanAdjustabilityPicking frequency |
| Dividers and Bins | Separates different stock-keeping units within a shelf or drawer. | Typical bin sizes: selected from small parts to full carton dimensions Label area: front-facing identification space | Improves item visibility, reduces mixing of similar parts, and speeds up counting and replenishment. | Fasteners, components, spare parts, and small packaged items | SKU quantityItem dimensionsLabel positionPicking method |
| Label Holders | Displays location codes, product identifiers, barcodes, or load limits. | Formats: magnetic, adhesive, clip-on, or slide-in Information: location, SKU, quantity, or safety details | Creates consistent visual identification and reduces search time and put-away errors. | Every rack level, bin, shelf, and pallet position | Label sizeScan distanceSurface typeReplacement frequency |
| Wire Partitions | Divides open rack or shelf areas into separate compartments. | Height: selected to match stored-item dimensions Installation: commonly clip-on or bolt-on | Prevents products from shifting or becoming mixed and makes each storage location easier to audit. | Loose parts, packaged components, rolls, and maintenance materials | Compartment widthItem stabilityAdjustabilityAccess |
| Aisle and End-of-Rack Guards | Protects rack ends and pedestrian-facing areas from vehicle impact. | Common construction: steel guardrail, post, or barrier system Placement: rack corners, ends, and traffic approaches | Improves traffic separation and helps prevent repeated impact damage at high-risk points. | Facilities using forklifts, pallet trucks, or powered stackers | Traffic patternImpact energyBarrier heightEmergency access |
