Q: Do I still have to wear a harness when your system is in place? A: If the roof being installed is a full hip, then no other fall protection devices should be necessary. However, the Stacker Bracket System is designed for use at the eaves and for small gables to provide a work platform and guardrail for the workers. Because roof designs vary, it is likely that no system will eliminate 100% of the fall hazards. Please consult our experts with any specific situations you need help with. Click here to contact us..
