Renfroe Model M is a multipurpose clamp used for positioning, sorting, erection and handling of prefabricated sections.
The split lower jaw enables the clamp to be particularly useful in handling structural shapes.
The Model M incorporates a “Lock Closed” feature which facilitates attaching the clamp to the member being lifted.
These clamps must be used in pairs, sets of pairs, or in a tripod arrangement for transporting plate horizontally. Handle is available on 8 ton clamp only.
