The Pelsue Model #AC-28R Manway Anchor 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 two, rounded jaw plates to be placed underneath the flange of the manway thereby anchoring the clamp to the structure. The grip of the jaw plates is adjustable in order to account for varying thicknesses of the manway flange. The Model #AC-28R will anchor to round manways having an outside flange diameter between 16 in & 28 in and a flange thickness of up to 1-1/4". The Model #AC-28R is constructed of steel and is coated with a durable electroless nickel plated finish.
