The S-5-Z is a two-piece aluminum clamp engineered for round “bulb-shaped” standing-seam metal roof profiles (≤ 7/8″ / 22 mm seam diameter). It delivers high holding strength for solar, snow retention, and utility mounts without penetrating the roof panel. Minis are available for lighter-duty attachments.
Purpose-Built Fit: Designed specifically for Zip-Rib®, BEMO, Kalzip® and similar bulb seams (≤ 22 mm).
High Strength, Low Intrusion: Two T-30 Torx round-point setscrews grip the seam; a top M8 bolt provides the attachment point—no through-fasteners.
Flexible Placement: Two-piece design installs anywhere along the rib for quick layout.
Tested & Certified: Standard S-5 clamps carry ICC-ES / IAPMO-UES / UL 2703 / DIBt approvals (see S-5 certifications).
System Options: Use S-5-Q when the bulb is oversized; use ZH at stationary halter locations; Z Mini for light/medium duty.
Manufacturer’s standard clamp warranty (S-5!).
Solar Module & Accessory Mounting: Pair with S-5 PV kits or utility mounts on compatible bulb seams.
Snow Retention: Attach S-5 snow systems to bulb-type ribs (use standard Z, not Mini, for most snow retention).
