The Pelsue Model #BC-16S Structural Beam Clamp is specifically designed to provide a portable mounting point for a Pelsue Model #FT-C70 Fall Arrest Tower. The telescoping tube sections are able to be extended, via the speed handle, allowing for two, angled jaw plates to grip underneath the flange of the structure thereby anchoring the clamp to the structure. The Model #BC-16S will anchor to structures having an outside flange width between 8-3/4" & 16" and a flange thickness of up to 1 in. The #BC-16S is also equipped with a swivel D-Ring that provides a compliant anchorage for a fall arrest system when the clamp is not used in conjunction with a fall arrest tower. The Model #BC-16S is constructed of steel and is coated with a durable electroless nickel plated finish.
