Renfroe Beam Clamp Model SEA Vertical Lifting, Locking
The Model SEA is a clamp used primarily for erection of structural beams. Configuration of the lower hook assembly and the over center position of the shackle permits a clamp to grip closer to the beam web, stabilizing the load and holding it with the web near horizontal for easy alignment of bolt holes.
The clamp incorporates a "Lock Open" and "Lock Closed" feature which facilitates in attaching and removing the clamp from the beam.
