Floor locks are mechanical components with an adjustable-height pad. They prevent portable equipment from rolling. Floor locks can be mounted to the underside of carts, lift tables, and platform trucks. They are recommended for use on level surfaces. Often, floor locks are used to immobilize a vehicle so that it may be loaded or unloaded safely. Floor locks are often described as heavy-duty or industrial strength. Features include easy foot-pedal activation, non-slip or non-skid brake pads, high-compression springs, and an easy-access release bar.
