Why Choose the S-5-ZF Mini Clamp?

A nut and bolt are often the required connection for certain utilities or bottom-bolted PV rails (Schletter, K-2, Everest) to a standing seam clamp. Choose the S-5-ZF Mini (“F” for “Flange”) for an economical, non-penetrating standing seam metal roof (SSMR) clamp for most “bulb” seam configurations such as ZipRib, BEMO and KalZip.

The slotted hole in the flange allows minor adjustment, making the ZF Mini ideal for walkways, module-level power electronics and a myriad of other utility mountings.

Stainless steel lock-nuts and several bolt sizes are sold separately.

The ZF 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-Z Mini for holding capacities of this clamp on different materials and seam specifics.

Choose the ZF Mini to mount a variety of utilities with a round “bulb” seam configuration and seam diameters ≤ 7/8” (22 mm).

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

How to Install the S-5-ZF Mini 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 and just below the bulbous portion (either side of the seam). Rotate the clamp into place over both the seam and insert. Hold this assembly in place with one finger, while tightening 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).

*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.
