Extend-Stem Threaded Caster for Ladders 32j912

Extended-stem threaded stem casters for ladders each have an extra-long threaded stem with a spring-loaded assembly. The threaded stem screws into a bracket on mobile ladders, platforms, and similar equipment used in warehouses, stockrooms, loading docks, and similar environments. When a load is applied to the equipment, the spring-loaded assembly contracts and lowers the equipment to the ground to keep it stationary during use. When there is no load on the equipment, the spring-loaded assembly expands to raise the equipment off the ground so the casters can roll. These casters have zinc-plated steel frames and double ball swivel bearings that allow the caster to swivel smoothly. Threaded stem casters are the most commonly used type of stem caster. They have a threaded stem on top that screws into a threaded hole, bracket, insert, or socket on a piece of equipment. The casters allow the equipment to roll, which reduces the effort it takes to move or reposition the equipment. Threaded stem casters are typically used to add casters on equipment where there is not enough room on the equipment’s mounting surface to attach a plate caster’s mounting plate.
