The Pelsue Model No. AC-34R & AC-28RX Manway Anchor Clamp is specifically designed to provide a portable mounting point for a Pelsue Model No. FT-C70 Fall Arrest Tower. The telescoping tube sections are able to be extended via the speed handle or HEX drive hub, 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 AC-34R will anchor to round manways having an outside flange diameter between 19 inches and 34 inches or 16 inches and 28 inches, and a flange thickness of up to 1.25 inches. The AC-34R & AC-28RX is constructed of steel and coated with a durable electroless nickel-plated finish. It provides a three-person tie-off and is easily installed.
