Super Deckenhalter

Perhaps not the most stylish, but perfectly handlen.
The rail system is awesome. The holder is screwed with 4 screws on the ceiling. The projector is mounted on the flexi Eblen strips.
Finally, the projector can simply be pushed and fixed in the existing rail of Deckenbefetigung. Thanks to the ball joint, it can be super align to the canvas. Perfect.
My Advice:
I bought it as needed (Beamer Discount Amazon Market Place). Instead of 79 EUR only 26 EUR. Missing only the screws. With me 4x M4x16. In Bauhaus for 1.60 EUR.
