This listing is for our 4" (Four Inch) Total Lock Casters with Gray Non-Marking Thermo Rubber Wheels. Total Lock Casters are the best casters to make your cart or equipment completely stationary by locking the swivel raceway and the wheels simultaneously with the push of one pedal. Our total locking casters are high-quality industrial casters. They have a heavy-duty double ball-bearing raceway; full dust covers to protect the ball bearings from debris, and a metal pedal that allows you to engage and disengage the brake quickly and easily. Thermo Rubber Wheels are fantastic wheels for a magnitude of applications. These wheels are shock absorbing, non-marking, non-marring, quiet, and easy to roll. Thermo Rubber Plastic Wheels have a soft thermo rubber tread on an industrial plastic core. These wheels are resistant to chemicals, solvents, wash down applications, all while protecting your floors and equipment. The plate size on these casters is a prevalent industry standard 2-3/8" x 3-5/8" overall size, seen on many institutional light to medium duty casters. The wheels come with a precision bearing that is maintenance-free and allows the caster to roll easily.
