WOCHN standing seam clamp AC-21 is rail-based clamp to standing seam metal roof for solar installation. It's commonly used on rould bulb standing seam metal roof, as: Kalzip, Bemo, Aluform, Euroseam®, Kingspan metal seam roofing. This clamp maintains the beautiful appearance of your standing seam roof with no harm to the roof material. No harm equals no penetrative that 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 set-screw for fast installation. Installation is as simple as placing the clamp on the seam and tightening the round-point setscrews to the specified tension to reach maximum holding strength. Rigorous load testing to ensure the longer lifespan and reliable.
