S-5-ZH™ Mini Clamp

Hinged Clamp Provides Versatile Solar Mounting on “Bulb-Shaped Seam Profiles ≤ 7/8” (22 mm) in Diameter.

S-5-ZH Mini Brochure

Need a Mounting Solution for Bemo, Kalzip®, Zip-Rib®, or Similar “Bulb” Seams?

Some bulb seam profiles utilize a one-piece stationary clip (or “halter”) to anchor the roof to the structure. This is typical of BEMO and Kalzip. (ZipRib generally utilizes a moveable two-piece clip.) When a stationary “halter” is used for roof attachment, the halter location must be avoided when using the S-5-Z. Alternatively, the S-5-ZH Mini can be used at halter locations, preserving roof design integrity while attaching near or directly over a halter.

The S-5-ZH Mini (“ZH” stands for Zip-Hinge) is specifically designed for round “bulb” seam configurations. Mount solar and other light-duty applications to “bulb” seams, such as BEMO, Kalzip®, Zip-Rib® and other similar profiles.

When mounted at a single-piece clip (or halter) location, the hinge design of the ZH Mini prevents the clamp from pinning the roof to the clip (halter), so roof panels slide freely over the clip (halter) preserving the roof’s freedom of thermal movement.

In like fashion to the Z-Mini, the ZH Mini can also be paired with the S-5-PVKIT for an economical, time and labor-saving rail-less (direct-attach™) solar mounting solution. Clamps and PVKITs as well as other solar racking can be placed where desired – no need to avoid clip (halter) locations.

The ZH Mini clamp attaches to the seam with a single setscrew. All Mini clamps undergo rigorous negative load normal-to-seam (uplift) testing. Please refer to our load testing for holding capacities of this clamp on different materials and seam specifics.

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

Additional options for this seam profile:

Sometimes the “bulb” diameter is larger than the specified dimension for the ZH due to errors in seam-closing. This can be corrected by hand, closing the seam to its proper dimension at clamp locations. Alternatively, the S-5-Q can be used when the (bulb) seam dimension is too large for the ZH. The Q is designed to fit these larger “bulb-shaped” profiles.

If you need a nut-and-bolt connection, see the S-5-ZF Mini.

Is the S-5-ZH Mini the Best Choice for Your Application?


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

Position the clamp and hinged insert at desired location along the seam. It may be necessary to place the clamp onto the seam first and then slide the hinged insert into the clamp body. Once the clamp is positioned over the seam, tighten the roundpoint Torx Drive (T30) setscrew (grub screw) to the specified tension. Then, affix ancillary items using M8 bolt (sold separately for the ZH 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.
