Telescopic Canopy Doors
For openings of any width and up to 80' high. Constructed in totally independent horizontal sections, Telescopic Canopy Doors do not require side guides. Any width opening can be filled with a number of sections installed side by side, and operated independently, in combination or in unison. Each section, normally 60' to 80' wide, consists of a vertically rising lower-and top-hinged upper leaf. The canopy is formed when the lower leaf moves up behind the top leaf and both swing out.
Grumman's Aircraft Paint Building at Bethpage, Long Island, uses two 82'-0" wide by 27'-0" high Fleming Motorized Telescopic Canopy Doors with two sets of unusual Air Filter Sliding Doors behind them.
