Description
S-5! Standing Seam Clamp (No-Bolt Version) S-5-Z Mini NB
The S-5-Z Mini NB is a light/medium-duty, non-penetrating clamp engineered for round “bulb” standing-seam profiles such as Zip-Rib®, BEMO, and Kalzip®. The NB (no-bolt) version ships without the top M8 flange bolt, letting installers choose bolt length/type per accessory. Its two-piece design installs anywhere along the rib and uses a single round-point setscrew to achieve high holding strength without piercing the panel.
Key Benefits
Purpose-Built for Bulb Seams: Designed specifically for round “bulb” seam geometries ≤ ~22–23 mm diameter (e.g., Zip-Rib®, BEMO, Kalzip®).
Non-Penetrating Grip: Round-point setscrew clamps to the seam without piercing panel coatings, preserving roof warranties.
Installer-Flexible NB Variant: Supplied without the M8 bolt so you can select the exact M8-1.25 hardware needed for your attachment.
Compact, Light-/Medium-Duty: “Mini” body with a single setscrew—ideal for utilities, PV attachments, and accessories that don’t require the full strength of a standard (two-setscrew) clamp.
Special Technology
M8-1.25 Top Thread: Built-in M8-1.25 threaded hole accepts S-5! PVKIT® studs, L-feet, or other accessories (bolt supplied separately with NB).
Two-Piece Body + Insert: Positions anywhere along the rib; insert and round-point setscrew develop high clamp forces on bulb seams.
Warranty
Manufacturer’s standard clamp warranty (S-5!).
Best Uses
Standing-Seam Metal Roofs (Bulb-Type): Mounting PV (with PVKIT® or rails), conduit, cable trays, small equipment, snow retention components, etc.
