The attic access bulkhead is design to fit around a standard 22.5” wide by 54” long attic opening and is used when trusses or ceiling joists need to be cut. The bottom truss chord or the ceiling joists are under tensions and prevent the roof from spreading and the exterior walls from displacing outward. The bulkhead attaches to the sides of the bottom truss chords or ceiling joists and resists the spreading (pulling apart) loads that exist in the truss bottom chord or ceiling joists thereby maintain the strength and integrity of roof system. The attachment points slide on the rails making them easily adjustable to the Attic Access Bulkhead, and can be positioned anywhere you wish. The Attic Access Bulkhead comes in pieces and is very easy and quick to assemble using standard tools. Position and secure the Attic Access Bulkhead first before cutting the trusses or ceiling joists. Custom sizes are also available.
