Expert Insights
Facility protection products — bollards, column protectors, corner guards, and wall guards — are the first line of defense against structural damage in any warehouse, distribution center, or manufacturing facility. The cost of a single forklift collision with an unprotected structural column can exceed $10,000 in repairs, not counting production downtime. These products pay for themselves after preventing just one impact incident.
Wall corners are the most frequently damaged structural elements in warehouses — forklifts clip them during turns, pallet jacks scrape them in narrow aisles. Corner protectors absorb the impact before it reaches the drywall or concrete. Sold in sets of two so both sides of the corner are protected.
Facility Protection Products in Action
Facility protection products are standard capital expenditures for every warehouse, distribution center, manufacturing plant, and commercial facility with vehicle traffic. OSHA general duty clause (Section 5(a)(1)) requires employers to provide a workplace free of recognized hazards — unprotected columns, corners, and pedestrian zones in vehicle traffic areas represent exactly the kind of hazards OSHA cites.
Corner protectors are deployed at every wall corner in forklift aisles, loading dock corridors, and high-traffic intersections. Sold in sets of two for complete corner coverage. Purchased by facility maintenance teams, warehouse safety coordinators, and property management companies.
Frequently Asked Questions
21 inch Corner Protector, Set of Two
Where should I install corner protectors?
Any exposed 90° wall corner in forklift or heavy traffic areas. The most common locations are dock doorways, aisle turns, cold storage entries, loading dock corners, and elevator lobby corners. Anywhere a forklift mast, pallet jack, or cart could clip a wall corner is a candidate.
What height should I choose — 21 inch or 42 inch?
The 21-inch height protects the primary impact zone for pallet jacks and hand carts — ideal for lighter-traffic corridors and office-to-warehouse transitions. The 42-inch height provides full-height protection against forklift mast and bumper impacts — required for loading docks, main aisles, and heavy-traffic warehouse areas.
Why are corner protectors sold as a set of two?
Each set includes two matching guards designed to be installed on both sides of a 90° wall corner. This provides complete protection regardless of the direction of impact. Mounting hardware is included for installation on drywall, concrete, or steel stud walls.
What material are corner protectors made from?
Thick high-density polyethylene (HDPE) in safety yellow. HDPE absorbs repeated impacts without cracking, transferring, or bouncing force into the wall structure. It won’t rust, rot, or degrade from UV or chemical exposure.
Do corner protectors ship for free?
Yes! All corner protector sets ship FREE to the Continental US (lower 48 states), typically arriving within 7–12 business days.
