Renfroe Model BD is a vertical lifting, non-locking clamp used primarily for steel warehousing and bench work where a locking type clamp is not essential.
The clamp is a low-cost, low maintenance tool that features lightweight and compact size. It is recommended for use and application where constant tension is applied to the lifting shackle throughout the entire operation.
