Gorter has supplied large RHT7014, 700 x 1400 mm roof hatches for a 50-appartment project on Lomonosovsky Prospekt in Moscow.
Gorter scissor stair extensions
An extension was supplied for each scissor stair because of the considerable height difference between the ceiling and the roof of the apartments. This extension provides 2, 3 or 4 extra treads in the plenum for direct connection to the scissor stair. The extension folds when the scissor stair itself is folded.
