BeamClamp® Components (Type BM)

The BM is a one piece, self adjusting clamp. This clamp adjusts between a specified clamping range and is suitable for both parallel and tapered flanges.

See specification charts

How It Works

How It Works

The BM is ideal in applications where flange thicknesses vary or are unknown as well as in seismic conditions (the 5/8” RF version of the clamp is seismically rated). Should the maximum clamping range be exceeded our BF2 and BG2 packers can be used to increase it.
