Roof Hatch - Ship Stair Access

All BILCO roof hatches are ruggedly built for long, dependable service. Covers feature a box-type design to support a 40 lb/ft2 (195 kg/m2) live load. The capflashing, fully welded corners, EPDM rubber gasket, fiberglass cover insulation and rigid fiberboard curb insulation ensure weathertightness and energy efficiency. Every roof hatch is designed with the proper number of compression spring operating mechanisms to provide smooth, easy, one-hand operation. Compression spring tubes are made from an anti-corrosive composite material and all other hardware is zinc plated and chromate sealed for corrosion resistance. The effortless one-hand operation to the fully open or closed position and the larger opening permits easier movement of maintenance personnel, tools and equipment.

Assembly and Installation
Installation of BILCO roof hatches is simply a matter of placing the hatch over the roof opening and securing it to the roof deck through the holes provided in the base flange. The integral capflashing readily accepts roofing felts for built-up roofing applications, and Bilco's patented Bil-Clip® flashing system simplifies installation in single-ply roofing applications.
