S-5-KHD Clamps

The S-5-KHD is the most heavy-duty and durable clamp in the S-5!® family. Designed primarily for new construction, this clamp fits the very distinctive profiles of the Lysaght® Klip-Lok® 406, McElroy Mirage, Metal Sales Clip-Loc and AEP Span Klip-Rib®. This clamp features an insert that is placed on the intermediate seam for extra hold.

Significantly stronger than anything else on the market for these profile types, the S-5-KHD clamp is geared for snow retention systems and other heavy duty applications in new construction where holding strength is critical. More strength means fewer rows of assembly, and roof warranties remain intact with zero-penetration S-5! technology. For load critical applications such as snow retention and attaching solar panels, the assembly should be specifically engineered to each individual project for maximum protection.
