Once the clamp assembly is permanently installed, the removable D-ring can be detached, allowing roofing materials to be installed over the flashing while the D-ring can be reused at another compatible anchor location. This design helps maintain the roof's weather resistance while extending the service life of the anchorage system.
The anchor is manufactured from corrosion-resistant zinc-plated steel and aluminum for durability in harsh outdoor environments. It includes roof flashing to help prevent water intrusion around the installation point and utilizes a bolt-and-clamp mounting system for secure attachment to structural wood members. The anchor is compatible with self-retracting lifelines (SRLs), vertical lifelines, and energy-absorbing lanyards, but it is not approved for use with horizontal lifeline systems.
