Floor Lock Adjusts to Accommodate Different Caster Rig Heights.
This floor lock offers adjustable heights to take up slack as wheels wear down, or make up for varying height differences when multiple casters are used on the same cart. Unit keeps working properly as spring and pad wear over time. Conveniently located foot pedal locks and releases easily. Bottom pad has a suction-cup surface for extra grip. Durable zinc-plated steel construction.
