Great item but with little effort could be made even better.
Good quality, easy build and installation.
Well pleased with item.
Design could be improved by making the hinges capable of 180 degree opening and another catch to retain it in the 180 degree open position.
Low level brush seal would also be a good optional item.
Also some form of standoff frame kit so has to be able to give clearance for protruding door handles in particular the type that require turning up to enable locking which in my external install clashed with the screens mid level frame cross piece.
Have made bespoke modifications to overcome my problems but others not capable of such will likely struggle or abandon fitment.
