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.
