Want to protect your walls and equipment?

A great add-on for your carts or equipment is our corner bumpers. Corner bumpers are designed to install on any piece of equipment or cart that could potentially damage walls and to child-proof sharp corners to prevent potential damage to children or animals caused by sharp corners. Our Gray 1" Thick by 3" long sides corner bumpers are non-marking and steel reinforced. CasterHQ's gray corner bumpers must be drilled into your equipment using 5/16" screws. Each Corner Protector has two holes on each side, totaling four holes per bumper. This corner bumper is commonly added to carts to prevent wall damage while rolling through hallways, hospitals, cruise ships, or tight spaces. The corner bumper will help prevent the corner of the cart from damaging walls or scratching areas that need protection. This is a fantastic upgrade to any cart, platform truck, or equipment as a precautionary method for protecting walls. Some customers will use these corner bumpers on their tables, countertops, and household items to prevent toddlers from accidentally bumping their heads on potentially hazardous home areas to protect the little ones from getting hurt. There are numerous applications for corner bumpers. Add them to your order for added protection.

Learn about our corner bumpers and why they are a must-have for any cart!
