The sold by Reflecta universal ceiling mount is not universally applicable. For the Projector TW-5x00 Epson and others HalteƤrmchen are running short. Without his own workshop in the house and fittings, this holder of these projectors are not used. Annoyingly, however, is the careless executed mounting the holding tube on the ceiling flange: The locking screws for the bayonet lock run by a dissolution process in the empty lot to short threads of the aluminum tube.
The projector can be solved with these screws under any circumstances from the ceiling flange, because subsequent reattachment after two screw and Solve operations no longer is certainly possible.
The user then lives with a sword of Damocles over his coffee table.
