Description
The WDH W75L75H90 roof hatch is intended for installation in roof slopes and enables the movement of people between the interior of the building and its roof. The high (90 cm) edge of the hatch leaves a lot of space for insulation and possible slopes on the roof. The protruding part of the hatch is still high enough to extend beyond the average snow cover with a safe margin. Communication takes place via an internal ladder (not included). The hatch has an internal ladder top mounting system (welded sheets with rivet nuts).
