The 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 and makes it an ideal horizontal locking plate clamp. It is recommended for use in pairs and sets of pairs. Handle is available on 8 ton clamp only.
