This product page offers caster sizes ranging from 3" thru 5" diameters all with 1/2" threaded stems combined with gray non-marking wheels. Threaded Stem Casters are a great way of converting your stationary unit or equipment into a mobile unit when you lack the space for a standard plate caster. Thermoplastic Rubber wheels also known as TPR Wheels are great for rolling over debris, obstacles, and absorbing shock and vibrations. Thermoplastic rubber has slightly less weight capacity compared to a steel wheel but it is our most popular and commonly used caster in a broad variety of applications to protect floors and equipment.
