The Pelsue Model #AC-34RX Manway Anchor Clamp is specific cally designed to provide a portable mounting point for a Pelsue Model #FT-C70 Fall Arrest Tower.

The grip of the jaw plates is adjustable in order to account for varying thicknesses of the manway flange. The Model #AC-34RX will anchor to round manways having an outside flange diameter between 19 in & 34 in and a flange thickness of up to 1-1/4 in. The Model #AC-34RX is constructed of steel and is coated with a durable electroless nickel plated finish.
