Product Detail

Product Description

RF03 Double Screw Standing Seam Clamp | Heavy-Duty High-Load Solar Attachment

The RF03 Double Screw Standing Seam Clamp is Ziyuan Solar's premier solution for heavy-duty applications. Unlike standard single-screw clamps, the RF03 features two round-point setscrews. This dual-point fixation doubles the friction interface with the roof seam, providing superior holding power against wind uplift and snow loads.

Designed for versatility, the RF03 is compatible with a wide range of standing seam profiles. The clamp body is extruded from high-tensile Aluminum 6005-T5, ensuring structural integrity over decades of service.

The non-penetrating design utilizes blunt-tip screws that securely grip the seam without piercing the metal. This preserves the roof's waterproof properties and manufacturer warranty.

RF03 Double Screw Solar Clamp featuring two side setscrews.
