FAQ

What do Caster City wire rack caster bumpers do?
They cushion caster stems to absorb impact energy during rack movement. This prevents damage to walls, doors, and fixtures in small retail spaces, reducing scuffs, dents, and repair costs.

What materials make up the bumpers?
Each bumper features a 13/16-inch thick, soft, non-marking rubber edge for superior shock absorption. A zinc-plated steel disc provides structural integrity and corrosion resistance, ensuring durability in demanding environments.

What is the diameter of the bumpers?
All bumpers measure 5 inches in diameter, offering ample coverage to protect against collisions in tight spaces like aisles or stockrooms.

What is the thickness of the rubber edge?
The rubber edge is 13/16 inches thick, providing a robust, flexible cushion that absorbs impacts without marking surfaces.

Which stem sizes do the bumpers fit?
Caster City offers five bumper variants to fit different stem sizes: 1/2 inch, 13/16 inch, 0.846 inch, 1 inch, and 1-1/8 inch. This ensures compatibility with a wide range of wire rack casters.

Which wire racks are compatible with these bumpers?
Our bumpers fit most standard wire racks with matching stem sizes, including:

• Metro Super Erecta: Widely used in retail and food service, compatible with 1-inch and 1-1/8-inch stems.
• Uline Wire Shelving: Common in warehouses, supports 1-inch and 13/16-inch stems.
• Regency Space Solutions: Fits 1-inch stems, popular in small stores.
• Shelving Inc.: Compatible with 1/2-inch and 0.846-inch stems.
• Nexel Wire Shelving: Works with 1-inch and 1-1/8-inch stems.

• Custom Racks: Fits any rack with casters using 1/2-inch, 13/16-inch, 0.846-inch, 1-inch, or 1-1/8-inch stems. Always measure your caster stem diameter to confirm fit.

Are the bumpers food-safe?
Yes, the non-marking rubber is non-phthalate and FDA-compliant, making it safe for food retail environments like markets, bakeries, or cafes. It resists moisture and cleans easily with soap and water.

What is the maximum capacity supported by the bumpers?
Bumpers support racks with a total load capacity of up to 1200 pounds (300 pounds per caster, assuming four 5-inch casters). They maintain performance under dynamic movement stresses.

What are the key applications in small retail?

• Inventory Transport: Protects walls when moving stock in tight stockrooms.
• Display Flexibility: Allows safe reconfiguration of sales floor layouts.
• Produce Carts: Shields fixtures in markets during restocking.
• Bakery Racks: Prevents marks from dough or tray carts.
• Pharmacy Shelving: Reduces noise and damage in quiet zones.

Do the bumpers reduce noise?
Yes, the soft rubber edge dampens caster clatter on hard surfaces like tile or concrete, creating a quieter shopping environment and improving customer experience.

How do you install the bumpers?
Installation is tool-free: clean the caster stem, slide the bumper onto the stem, and press firmly for a snug fit. Pliers may assist with tighter fits. Test roll to ensure stability.

Are the bumpers suitable for rough or wet floors?
The rubber edge performs well on rough surfaces and resists moisture, making it ideal for wet environments like florist shops or kitchens. Pair with rubber or polyurethane casters for optimal grip.

Can the bumpers be used with custom casters?
Yes, as long as the caster stem matches one of the five sizes (1/2″, 13/16″, 0.846″, 1″, 1-1/8″). Contact Caster City at 800-501-3808 or sales@castercity.com for custom solutions.

How do I maintain the bumpers?
Wipe monthly with soap and water to remove dust or grime. Inspect quarterly for cracks or wear. Replace if damaged to maintain protection. The zinc-plated disc resists rust, extending lifespan.

Do the bumpers work with non-retail applications?
While designed for retail, they suit home garages, offices, or libraries with compatible wire racks. They protect surfaces during movement of file carts, book trucks, or storage units.

What makes Caster City’s bumpers unique?
Our bumpers combine a thick, non-marking rubber edge with a durable zinc-plated disc, offering superior impact resistance and corrosion protection. Five stem size options ensure broad compatibility, and our manufacturing expertise allows custom tweaks. Visit our wire solutions page for more.

How do I choose the right bumper for my rack?
Measure your caster stem diameter (1/2″, 13/16″, 0.846″, 1″, or 1-1/8″). Match to the bumper’s hole size. Check rack load (up to 1200 pounds) and floor type. Contact us via our contact page for guidance.

Can I pair these with Caster City casters?
Absolutely. Our bumpers pair seamlessly with our 5-inch casters, including polyurethane or rubber wheels for grip. See options at our casters page. Bundles may optimize performance.

Do the bumpers fit racks from major retailers?
Yes, they work with wire racks from Costco, Sam’s Club, Home Depot, and similar, provided the caster stems match our sizes. Common brands like Metro and Uline are fully compatible.
