发明名称 Ladder ridge anchor and attachment and stabilizer system
摘要 A ladder ridge anchor device and system incorporating new and improved mechanisms are disclosed herein for attaching a ladder to a roof ridge anchor to secure a ladder over the roof ridge of a building. These improvements also allow the user to easily adjust the position of the ladder relative to the roof ridge anchor to facilitate work on and access to the roof or other building areas. Stabilizing components help prevent lateral movement of the ladder with respect to the attached ridge anchor and extension components elevate the ladder and roof ridge anchor off the surface of the roof.
