Heavy-Duty Adjustable-Height Floor Lock: For 4 in_5 in_6 in Wheel Dia.

Heavy-duty adjustable-height floor locks have cast steel or stainless steel bodies and provide more strength and abrasion resistance than general purpose floor locks. They have adjustable-height friction pads that allow them to be used with casters in a range of heights. The height of the pads can also be adjusted as the pads wear over time to help maintain proper locking and unlocking action. The bottoms of the friction pads have suction cups for increased grip. The locks have a top mounting plate for installing them on carts and other equipment.

Floor locks keep carts, mobile racks, or other wheeled equipment stationary. They are an alternative to caster-mounted brakes. The locks are typically mounted between two swivel casters on carts with a single pair of swivel casters, or they are mounted on diagonal corners on carts with four swivel casters. The locks have a foot pedal that users step on to engage a spring-loaded brake pad that presses against the floor to create friction and prevent the caster wheels from moving. The extended height of the lock should exceed the mounting height of the casters it will be used with by 1/16" to 1/4".
