THE ADJUSTABLE POSITION FLOOR LOCK USES A SPRING-LOADED RUBBER FOOT PAD TO IMMOBILIZE EQUIPMENT. IT IS COMMONLY USED TO KEEP FRAMES FROM SHIFTING AND HAS A FOOT THAT CAN ADJUST UP TO 2.75 INCHES (69.85MM), ALLOWING GREATER DESIGN FLEXIBILITY. THE ADJUSTABLE POSITION FLOOR LOCK HAS A FOOT RELEASE LEVER AND COMMONLY MOUNTS TO A T-SLOT PROFILE SIDE USING A POSITION FLOOR LOCK BASE PLATE. THERE IS A MINIMUM WEIGHT REQUIREMENT OF 70 POUNDS (400 KG) NECESSARY TO PROPERLY IMMOBILIZE EQUIPMENT. BY ADJUSTING THE TENSION NUT, THE HOLDING FORCE CAN BE INCREASED FROM 70 (400 KG) TO 120 (534 KG) POUNDS.
