Seitz / Dometic Heki Skylights Guide

Article by - Caravans Plus

Formally know as Seitz the Heki Skylight family has been rebranded under the Dometic name. Available in 3 different sizes the Heki range of RV hatches are commonly found in the Australian caravan market and all include the same key features.

  • A transparent acrylic lid with multiple opening settings to provide an abundance of natural light and fresh air.
  • The signature bad weather setting continues to provides ventilation while restricting rain entry.
  • For added comfort the slimline internal frames incorporate insect screens and block-out blinds to ensure complete control of your environment.


    Mini Heki Skylight - 400mm x 400mm

    The most compact in the Heki Range is the Mini Heki. This square skylight has a lightly tinted dome and internal frame which includes a retractable insect screen and block-out blind. This skylight fits into a 400mm x 400mm roof opening and can be identified by its internal frame which measure approx. 520mm x 520mm.

    In recent years Dometic Australia has decided to no longer offer the Heki S. While spare parts are still available here, complete units can only be found in the international market.

    In regards to spare parts the most common request is for individual components like the insect screen or blind. Unfortunately these are only available in the form of the complete internal frame, we have parts diagrams available showing the breakdown of available parts.

      The hinges on my 12year old hatch have broken and I have not worked out a way to do a repaire. I can't find a make on the frame or acrylic dome and there are several different sizes listed on the web. The only dimension I can confirm is the clear sky opening of 540x840. The hatch is in good condition otherwise. If a half hinges repair is not available I will need to know what is the replacement dome assembly. Thanks Ian
