Why Choose the EF Mini Clamp?

Sometimes you need a nut-and-bolt connection to the clamp rather than threading the bolt into the clamp directly. This is why we created the S-5-EF Mini clamp the right choice for a traditionally dimensioned, double- folded standing seam. The EF Mini ( “EF” is for European Flange) is an economical, non-penetrating, standing seam metal roof (SSMR) clamp. With a slotted hole in the flange, the EF is ideal for the attachment of bottom-mount solar rails and a broad spectrum of other utility mountings. Stainless steel nuts and several bolt sizes are sold separately. 

The EF Mini has a single setscrew for medium or light-duty applications, such as solar or satellite dish mounting.

Please refer to the load testing of the S-5-E Mini for values of this clamp. 

Choose the EF Mini to mount a variety of utilities with nominal seam dimensioning (<½” seam fold (13 mm) to your double-folded, standing seam metal roof.

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

Does the S-5-EF Mini Clamp Fit Your Roof Profile?

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

Place the clamp at the desired location on the seam with the lower “lip” of the clamp throat beneath the seam fold. Tighten the roundpoint Torx Drive (T30) setscrew to the specified tension. The slotted thru-hole in the flange accommodates bolt diameters of up to ⅜” (10 mm). (Bolt and nut sold separately as needed).

*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.
