ABSTRACT:
A perimeter net system with the capability of rotating between an open and a close position is described. The perimeter net system includes a support arm, a lock arm, a support arm storage lock, a support cable, a pivot bracket, and a net. These components work together to allow a safety net system to easily be folded against a building for repairs or in inclement weather conditions. The support arm rotates to a closed position on the pivot bracket, and the lock arm adjusts with the support arm. Once in the closed position, the support arm storage lock secures the support arm and the lock arm in place.
