S-5-Z Clamp

The S-5! Z Clamp is specially designed for “bulb”-shaped standing seam roof profiles, such as Zip-Rib®, BEMO, Kalzip®, and similar configurations having rounded seam lobes. It accommodates bulb-seams up to 7/8″ (22 mm) in diameter. The Z Clamp is constructed as a two-piece unit so it can be installed anywhere along the rib without disturbing the seam’s anchor base. It features two round-point Torx-T30 stainless skeleton setscrews that grip the seam without penetration, preserving roof coating integrity. The standard version includes an M8 bolt for accessory mounting; there is also a Mini version with one setscrew and minimal height for lighter duty applications. The standard Z Clamp is strong enough for snow guards, solar modules, and other heavy rooftop loads.

Key Features:

• Designed for round “bulb” seam configurations up to 7/8″ (22 mm) diameter
• Two-piece clamp design installs anywhere along the length of the rib
• Dual Torx-T30 round-point stainless setscrews; standard includes M8 bolt
• Non-penetrating design preserves roof seams and coatings
• Mini version available: one setscrew, shorter clamp body, no bolt, for lighter loads

• Seam type compatibility: Bulb-shaped standing seams (Zip-Rib, Kalzip, etc.) with diameter ≤ 7/8″ (22 mm)
• Setscrews: Two round-point Torx-T30 stainless steel (standard version); Mini version uses one
• Bolt: M8 bolt included in standard version; not included in Mini version
• Material: Structural aluminum body; stainless steel hardware
• Includes: Clamp body, two setscrews, M8 bolt (standard), Torx-T30 bit tip

• Confirm your roof’s seam profile is bulb-shaped with diameter up to 7/8″ (22 mm).
• Position the insert component below the bulb of the seam at the desired height.
• Place the clamp body over seam and insert.
• Hand-thread the two setscrews until clamp fits snugly; in Mini version use one setscrew.
• Tighten setscrews to manufacturer torque specifications.
• Attach accessory via the included M8 bolt (standard version) if needed; inspect after load or weather events.

Q: What profiles are compatible with S-5! Z Clamp?
A: Bulb-seam standing roof profiles such as Zip-Rib®, BEMO, Kalzip®, etc., with seam diameter ≤ 7/8″ (22 mm).

Q: What is the difference between the standard Z and Z Mini versions?
A: Standard has two setscrews and includes an M8 bolt; Mini has one setscrew, smaller body, and excludes the bolt.

Q: Does the Z Clamp damage roof seams or coatings?
A: No. It uses round-point setscrews that dimple rather than pierce the metal, preserving coatings and warranties.

Q: What types of loads is the Z Clamp rated for?
A: S-5! publishes load test data for both pull-up (normal) and drag (parallel) load orientations; the standard Z is rated for heavy duty use, snow guards, solar modules, etc.
