The S-5! WindClamp™ DL is a purpose-built external seam clamp that installs over the standing seam at set intervals to help prevent male-to-female seam separation and clip pull-off on Double-Lok® and similarly-dimensioned profiles—significantly increasing roof wind resistance without intrusive retrofits.
Boosts Wind Uplift Capacity: Independent testing shows increased failure pressures—as much as 300%, depending on panel profile, gauge, and purlin spacing.
Retrofit-Friendly: Installs from the exterior with no tear-off or interior disruption; ideal for bringing older roofs closer to current code/insurance requirements (ASCE 7-16, FM 1-31 concepts).
Protects Roof Integrity: Preserves thermal cycling, existing roof warranties, and avoids costly structural changes like adding clips or increasing panel gauge.
Clamp-to-Seam Design: Low-profile body slides over the seam; a single setscrew is tightened to the specified tension to lock the seam against separation.
Manufacturer’s standard S-5!® product warranty.
Standing Seam Metal Roofs: MBCI® Double-Lok® and similarly dimensioned double-folded seams on commercial, industrial, and institutional buildings in higher wind regions.
