Abstract:
A system and method for establishing a safe room environment within an attic space utilizing a typical folding attic stair and door assembly. The system includes components that retrofit to an existing folding attic stair in a manner that allows the user to draw the attic stair up behind them and to secure the attic door panel closed and locked while the user is within the attic space. The components include a retractable lift cord attached to a middle section of the attic stair, and a lift rod attached to the attic door. Brackets and frames positioned on the attic door and door frame allow the user to pull up to fold and raise the stair into the attic space. A lock may then secure the attic stair closed preventing access from below. Methods for installing the system and using the system are provided.
