The SCA Under Hoist Stand is ideal for the professional trade workshop. This auxiliary under hoist stand is designed for supporting exhaust systems, shock absorbers and other vehicle components during hoisted vehicle repair. Auxiliary under hoist stands function as an extra pair of hands to hold heavy components in place, freeing up mechanics hands to assemble or disassemble. These portable stands are perfectly suited to muffler and transmission workshops. WARNING: Under hoist stands provide partial support for components only - they are NOT designed to support a vehicle. WARNING: Under hoist stands must be used in conjunction with a car lift hoist and are not intended to be used to support a vehicle.
