Retractable ladders

Integrated mounting of retractable ladder

Staka has made the installation of a roof access hatch significantly simpler. You can simply hang the retractable ladder from the ceiling using the supplied brackets. The installation frame (between the roof and the roof access hatch) features openings allowing the retractable ladder to be installed at a later stage if desired.

The roof access hatch is installed during the structural construction phase, after which you waterproof the roof. The retractable ladder generally follows at a later stage of construction, the fit-out stage. This means the ladder is clean and undamaged upon completion.

You don't need to construct anything extra or drill into the ceiling to hang up a Staka retractable ladder. This makes installation much simpler compared with retractable ladders, pull-down ladders, and folding ladders made by other manufacturers.

Installation in lowered ceilings

If you are installing the roof access hatch with retractable ladder in a space with a lowered ceiling, and the distance between the ceiling and the roof is more than 350 mm, you should opt for the roof access hatch model DL147 (1400x700 mm) with a plenum space bridging element. With this strong aluminium construction, you can install the necessary extra steps.

The retractable ladders meet European standard EN 14975 and are fitted with a pre-assembled telescopic handrail. The strong cast aluminium steps also feature anti-slip profile. 

Convenient installation

The roof hatch with hatch box is placed through the roof opening from above. Finishing of the entire roof opening is complete, just like that. Directly afterwards, or during completion of the building, it is a 10-minute job to attach the retractable ladder to the hatch box from below using the provided mounting points.

The roof hatches with integrated retractable ladder are available in the following dimensions:

  • 900 x 700 mm
  • 1400 x 700 mm

As a budget alternative, you can choose the Staka EasyAccess roof access hatch. This roof hatch is furnished with two clamping locks. The EasyAccess roof hatches are simple, yet functional and safe, and are also available with retractable ladder in the sizes 900x700 and 1400x700 mm.
