Super Anchor Z-Purlin Permanent Roof Anchor for Metal Building Purlins
The Super Anchor 2811 is a permanent Z-purlin roof anchor kit in 11 gauge stainless steel with EPDM flashing, gray stem cover, zip tie tether strap, and fasteners. It bolts to common Z-purlins and its stem height clears high rib metal roofing panels. A box of 6 (1016) is listed separately.
The anchor stem features a collapsible design that arrests a fall while reducing the shock load transferred to the Z-purlin by several hundred pounds. The universal size has four mounting positions to fit all standard Z-purlins, and it is fabricated from 11 gauge stainless steel.

Who Needs This Product
The Z-Purlin anchor is a permanent fall arrest anchor for workers building and servicing light commercial metal buildings with Z-purlin framing. High rib metal roofs are among the most dangerous surfaces when wet or icy, and this anchor gives a compliant tie-off during construction and long term service. Complete the system with a full-body harness, a connecting device, and a competent-person layout.
