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 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, this 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.


The S-5-KHD clamp is furnished with the hardware shown above. A structural aluminum attachment clamp, the S-5-KHD is compatible with most common metal roofing materials excluding copper. All included hardware is stainless steel. Please visit www.S-5.com for more information including CAD details, metallurgical compatibilities and specifications.

Insert Length

The S-5-K HD 3″ insert is only for use on existing construction and placed at the eave. This is done by sliding it up into the seam. This installation can only achieve one row of snow retention.

The S-5-K HD 6″ insert is only to be used for new construction. The insert is snapped into the under side of the roof panel before installation. Care needs to be taken to avoid roof clip locations.

Pricing subject to change at will.
