S-5-B Brochure

Why Choose the B Clamp for Your Copper Roof?

Architects and roof designers choose copper roofing for its timeless elegance and durability. The S-5-B (or S-5-BSF) allows you to maintain that theme when mounting snow guards or utilities on the roof. The visual appeal of copper roofing also makes it a superior roofing type. The B (“B” is for Brass) is designed for double-folded, copper standing seam paneling.


Minis Available

The B Mini clamp is a more economical solution for lighter-duty attachments where Herculean holding strength is not required. The Mini clamp is a bit shorter than the standard B with one setscrew rather than two

Rigorous load testing is performed on both standard and Mini clamps. Negative load normal-to-seam testing (pull-up) is performed on all Mini clamps, and parallel-to-seam testing (along the seam or drag load) is performed on all standard clamps.

Choose the B to mount a variety of utilities, such as rooftop lighting, solar arrays, lightning protection and other appurtenances to your copper roof. Be sure to check out the many other features on the clamp overview page.

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

How to Install the S-5-B 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 B clamp; sold separately for the B 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.
