S-5-N & Mini Brochure

Your Mounting Solution for 1” (25 mm) Nail-Flange Metal Roof Profiles

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

The N fits popular 1″ nail strips, such as: Taylor Metals’ Easy Lock™, ASC Building Products’ Skyline Roofing®, McElroy Metals’ Meridian, New Tech Machinery’s FF100 and roofing types with similar profiles.

For nail strip profiles with 1.5” seam height, see “S-5-N 1.5.

Minis Available

The N 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 to mount to nail flange metal roof profiles with a base of rib dimension ≤ .82” (20 mm). Check also the S-5-NH 1.5 for matching to other seam dimensioning, such as NewTech FF150 and VicWest Prestige. Be sure to check out the many other features on the clamp overview page.

Is the S-5-N the Right Choice for Your Roof Profile?

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

Place the insert against the base of the seam opposite the overlap side at the desired location. Place the clamp over the seam and insert. Tighten the Torx Drive (T-30) setscrews against the insert to the specified tension. Then, affix ancillary items using the bolt (provided with standard N clamp; sold separately for the N Mini). 

Special design of the S-5-N’s angled wall and nose engages the angular overlap portion of nail strip 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.
