Hook Clamp Assemblies

Jergens Hook Clamp Assemblies feature moderate to heavy-duty holding power in close quarters. When released, the hook clamp swings quickly and easily out of the way for fast maneuvering of work. Their spring-loaded shank allows for quick clamp release.
 
Alternative to the above assembly, we also offer Hook Clamp Assemblies that feature a flush-mounted socket screw instead of an acorn nut. They are designed for limited space applications and moderate holding power.
