Renfroe Plate Clamp Model FRD Vertical Lifting, Locking
The Model FRD is a vertical lifting clamp that incorporates two Model FR clamps into one and is used for heavy duty work where it is desirable to spread the gripping surfaces with two points of contact.
The clamp contains two 'Lock Closed' mechanisms which are activated by a single chain and a manually operated 'Lock Open' mechanism.
