S-5-T™ Clamp

Designed for “T”-Shaped Seam Profiles Up to 1.3” (33 mm) Horizontal Dimension.

S-5-T & Mini Brochure

An Attachment Solution for "T"-Shaped Standing Seam Profiles ≤ 1.3” (33 mm)

The S-5-T is specifically designed for profiles featuring a “T”-shaped seam configuration. Easily install the two-piece design anywhere along the seam.

Mount snow guards and other heavy-duty applications to profiles, such as McElroy Metal 138T & 238T, Centria SRS 2 & SRS 3, Imetco Series 300, GreenSpan RidgeLine, Metal Sales T-Armor and other similar profiles.

This non-penetrating, standing seam metal roof clamp can also be used on architectural “single-fold” or “angle- seam” profiles with a horizontal projection of 5/8” (15 mm) or less.

Minis Available

The T 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.

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

Is the S-5-T the Best Choice for Your Roof Profile?

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

Using the ergonomic finger grip “tail” of the insert, position the insert at the desired location against the base of the seam (either side of the seam). Rotate the clamp into place over both the seam and insert. You can hold this assembly in place with one finger, while tightening the roundpoint Torx Drive (T30) setscrews to the specified tension. Then, affix ancillary items using the bolt (provided with standard T clamp; sold separately for the T-Mini).

*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.
