LXW-B Upper Hatch (Insulated R=5.9)
The upper hatch prevents attic dust form accumulating on the hatch and steps of the closed ladder. It improves the overall insulating parameters and tightness of the ladder on which it is installed. Available for ladders LWN, LWP, LWT, LWF, OWM, LMS. For the LST model ladder, the extension box should be installed prior to the upper hatch.
