[TOTAL ENCLOSURE DUST COVERS] Say goodbye to gritty and jammed bearings. Unlike standard open-bearing casters that easily trap hair, dust, and debris, our 4 inch caster wheels feature an exclusive black plastic total enclosure design. This completely isolates the rotating shaft and bearing center from foreign objects, significantly extending the lifespan and ensuring a permanently smooth roll.
[SILENT RUBBER & FLOOR FRIENDLY] Engineered with high-strength industrial composite rubber, these heavy duty casters glide silently and smoothly. They are strictly will not leave scratches on hardwood, tile, or epoxy floors. The deep anti-slip tread patterns provide exceptional grip, making them highly controllable even on slippery surfaces or in noise-sensitive environments like offices and labs.
[DOUBLE LOCK BRAKE SYSTEM] Maximum safety for your equipment. Each of the 4 swivel casters is equipped with an independent dual-locking mechanism. A single press of the brake pedal simultaneously locks both the wheel's forward rolling and the top plate's 360-degree rotation, keeping your heavy workbench, tool box, or furniture firmly anchored in place without any sliding.
[1000 LBS HEAVY DUTY CAPACITY] Built for rigorous daily use. This set includes 4 swivel casters with brakes. Each 4 inch wheel boasts a robust load-bearing capacity of 250 lbs, combining for a total support of 1000 lbs per set. It provides reliable and stable mobility for industrial carts, heavy furniture, machinery, and warehouse dolly setups.
[COMPLETE INSTALLATION KIT] Save a trip to the hardware store. We provide everything you need for immediate assembly. The package includes 4 heavy duty caster wheels, 2 complete hardware kits (1 set of screws and 1 set of bolts and nuts for different mounting surfaces), 1 small wrench, and 1 pair of installation gloves to protect your hands during the process.
