For installation of air conditioners or rooflights in cut-outs on flat vehicle roofs, which are larger than the standard opening size of 400 x 400 mm.
The adapter frame is made of high quality aluminum and allows a perfect seal as well as a clean surface. Due to its external dimensions of 520 x 520 mm, existing roof cut-outs can be reduced to the required 400 x 400 mm for the installation of Dometic FreshJet air conditioning systems or rooflights. If possible, an existing roof opening should not be larger than 450 x 450 mm, since otherwise the necessary support surface for weight and especially large-scale sealing is no longer sufficient.
Part of the delivery is just this adapter frame!
