WOCHN standing seam clamp AC-28 is rail-based clamp for pv-installation on standing seam metal roof. It is specifically made for single folded standing seam metal roofs in 90 degree with a horizontal width of 14-25mm.This clamp maintains the elegance of your standing seam roof with no penetrate to the roof material. No penetrative means weatherproof for the roof to ensure the rooftop longer lifespan.And also ensure that must be mounted to the roof with permanence and durability. Pre-assembled two side-bolts for quick mounting. Installation is as simple as placing the clamp on the seam and tightening the round-point side-bolts to the specified tension to reach maximum holding strength. Rigorous load testing to ensure the longer lifespan and reliable.
