Initially thought "oh dear never stops at this windy sticks", but ultimately fits perfect for my Epson EH-TW3200, which is not indeed the smallest projector. Before I felt confident the projector to hang off I've even self drangehängt and my 80kg's has held, so I thought is also Beamer (with 10-15kg or so) keep well and now that part is already hanging perfectly for 6 weeks. At my reinforced concrete ceiling fixed drilled I have the bracket with: 4x "normal" Fischer concrete plugs S6 (drill diameter: 6 mm - dowel length: 30 mm - Min hole depth. 40 mm - for screws Size: 4-5 mm) and then with four 5x35mm Spax screwed. As I said holding my 80kg (ok only briefly, because I could not keep me long-min) from. For mooring the projector will be suitable screws that fit perfectly into the holes provided in the housing of the TW3200 + thread - you have here but to be second. So after some initial misgivings, full buy recommendation
