Gorter® Flat Roof Access Hatch - RHT standard

Gorter® Flat Roof Access Hatch - RHT standard

New generation Gorter RHT roof 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.
