S-5-EF™ Mini Clamp

The answer to this question varies with the load direction, the seam profile, the roof material and the clamp model.

These variables result with a wide range of holding capacities from ±300 lbs (235 kg) to ±4,000 lbs (1800 kg). This is why for critical applications it is important to correctly identify the roof panel, seam type, gauge, etc along with the recommended seam clamp for the specific roof. When used on some “applied cap” architectural type seam styles, S-5! may yield low load-to-failure results as compared with integrated seam profiles. Always check our load table to verify the correct allowable holding strength on your specific roof type.

All S-5! clamps undergo rigorous mechanical tensile load testing. We typically test in two load directions: Negative load normal-to-seam testing (pulling-up), and parallel-to-seam testing (drag load). We actually developed these test protocols back in 1992 as ASTM has no prescribed test procedures for this type of testing. For more on our testing protocols and results, visit this link and check out our video.

You can request our Clamp-to-Seam Gauge Tool from your Authorized S-5! Distributor or directly from S-5! The most common seam geometries are included within this fitment tool and it is cost-free. Keep it for future fitment checking. Request your tool here.

If unsuccessful using the gauge tool, the fastest and easiest way to find the clamp you need is to visit our CLAMP TO SEAM TOOL on our website which takes you through a pictorial process of determining the proper clamp. 

When you first get to this page it will ask you if you know the manufacturer and specific profile of your roof or if you don't know these things. Once you have selected the latter option, you will be brought to a page of diagrams that easily let you identify the most common panel seams found in the market today and the corresponding clamps that should fit that seam profile.
