Tractel Standing Seam Roof Clamp with 30 ft. Blocfor AES Leading Edge Self-Retracting Lifeline – N650/3

The Tractel N650/3 Standing Seam Roof Clamp System combines a non-penetrating anchor with a 30 ft. Blocfor AES Leading Edge self-retracting lifeline (SRL) to deliver a complete fall-protection solution for metal roof applications. Designed specifically for standing seam roofing, this system provides reliable, code-compliant anchorage without compromising roof integrity.

The N650 standing seam clamp securely attaches to metal roof seams using a precision clamp design—no drilling or fasteners required. This prevents leaks or structural damage while ensuring a solid, reusable anchorage point. Paired with the Blocfor AES Leading Edge SRL, it offers smooth cable retraction, controlled braking, and enhanced protection when working near or over edges.

Built for professional use, this system provides safety, mobility, and peace of mind for contractors, roofers, and maintenance crews working at height. It meets OSHA and ANSI requirements for fall arrest and leading-edge applications.
