Gorter roof hatches with scissor stairs provide practical and safe access to flat roofs for maintenance work or other purposes. The roof hatch can be installed on flat roofs with a maximum pitch of 30°.

The Gorter combination of roof hatch and Large Electric scissor stair provides generous access to the roof and is available for ceiling heights of max. 3,000 or 3,500 mm. The roof hatch has an opening of 700 x 1,400 mm.

Large type: max. ceiling height 3,000 mm

Large H type: max. ceiling height 3,500 mm

A powerful motor drives the Gorter electric scissor stairs. The system comes with a control unit and a wireless RF remote control as standard.

Roof hatches combined with an electric scissor stair are ideal for applications where occasional but also frequent access to the roof is required. When the scissor stair is folded, you always have free space under the hatch.

The new generation RHT roof hatches feature an extremely strong and patented construction. Thanks to several modifications, the roof hatch is even more resistant against unexpected extreme loads, both during construction and in general use.

Improved features and functionalities of the indestructible and sustainable RHT roof hatch:

Made and Designed in Holland
New and improved, patented indestructible construction
Trusted, with CE(ETA) certification
Now available directly from stock in sizes up to 1000 x 3000 mm
Fully standardised to metric dimensioning

The Gorter RHT roof hatch has a fully thermally broken curb and cover, and a proven high insulation value of U_w ≤ 0.319 W/(m².K) This minimises the chance of condensation forming and guarantees energy cost savings.
