The "SKYHOOK" is designed as a permanent Fall Arrest Anchor(SFAA) to be used by workers while working on a sloped truss roof. The unit will provide a secure anchor point for a lifeline. The SFAA will arrest a workers fall should they cross over the edge of the roof in a vertical fall and also restrain a worker from slipping or falling while on the roof, if used in the proper manner.
