Hollaender (Cincinnati, OH) developed the 47R in 1-1/2” IPS size, wide-footprint flange used to attach solar racking systems and railings to narrow gauge metal roofing. The new design is ideal for applications on narrow gauge corrugated metal where the load must be spread out further and where numerous fasteners are required. The 6” by 8-1/2” spreads the mounting load over a larger surface. It ensures adequate pullout force and torque resistance by the use of twenty-two 5/16” mounting holes that take 1/4” TEK screws.
