Designed specifically for the Metal Building industry, our Z-Purlin provides an easy to install anchorage device that includes attachment bolts. The stem height of the anchor is compatible with high rib roofing panels and blanket type insulation. Waterproofing is achieved using a high quality E.P.D.M. gray colored flashing boot and matching stem cover that has an aluminum flange allowing it to be configured easily to any shape panel. The anchor stem features a collapsible design that will arrest a fall and reduce the shock load to the Z-Purlin by several hundred pounds. Universal size has 4 mounting positions to fit all standard Z-Purlin sizes. The anchor is engineered to fit all common size Z-Purlins, with custom sizes available upon request. Fabricated using 11-gauge stainless steel, our Z-Purlin anchor can be installed onto a purlin before or after erecting and will provide a safe tie-off during the construction period. But the real benefits are realized by workers who must perform service or maintenance. Few surfaces are as dangerous as a high rib metal roof panel when it is icy, wet or has an accumulation of algae. A cost-effective solution to one of the industry's most dangerous hazards. Supplied without caulking or flashing fasteners.
