S-5-N 1.5 & Mini Brochure

Need to Mount Snow Guard Systems, Heavy-Duty Applications to Taller Nail-Flange Profiles?

The S-5-N 1.5 (“N” stands for nail strip) is a non-penetrating, standing seam metal roof (SSMR) clamp.

The N 1.5 is the right choice for 1.5″ (38 mm) nail strips, such as: Bridger Steel 1.5” Tru Snap, Schlebach 1.5” NailStrip, Sheet Metal Supply NS 1.5”, Sheffield Metals SMI 1.5” and roofing types with similar profiles.

(For nail strip profiles with 1” seam height, see “S-5-N.”)

Minis Available

The N 1.5 Mini clamp is a more economical solution for lighter-duty attachments where Herculean holding strength is not required. 

All standard and Mini clamps undergo rigorous load testing. Negative load normal-to-seam testing (pull-up) is performed on all Mini clamps, and parallel-to-seam testing (drag load) is performed on all standard clamps.

Choose the N 1.5 to mount to nail flange metal roof profiles with a seam base dimension ≤ .50” (12.7 mm). (For nail strip profiles outside this dimension, please see the “S-5-NH 1.5”).

Be sure to check out the many other features on the clamp overview page.

How to Install the S-5-N 1.5 Clamp on Your Roof Profile*

Installation is as simple as placing the clamp on the seam and tightening the round point Torx Drive (T30) setscrews to the specified tension. Then, affix ancillary items using the bolt (provided with standard N 1.5 clamp; sold separately for the N 1.5 Mini)

Special design of the S-5-N 1.5’s angled wall and nose engages triangle type rib profiles during installation.

*See more detailed installation instructions in the PDF download below.

*S-5! clamps may be moved in the event of initial misplacement. However, due to the ensuing oxidation process which acts as a natural thread lock, we can express no opinion to the performance of a clamp once it has been removed and reinstalled or the ability to remove the clamp after this process has occurred.
