This is a projector ceiling mount for sale. It's over 10 years old and has scratches and discoloration of the resin. I purchased it used from the seller when I won a projector in an auction. This mount was used with a DLA-X90R (body weight ≈ 15kg). The mount's weight capacity is 23kg. I also temporarily used it with a DLA-V80R, but as the body weight is 25kg, I replaced it with a Kikuchi mount, so this one is no longer needed. Also, as shown in the last photo, the anti-rotation screw for the joint between the main mount and the ceiling bracket was missing from the beginning (I don't know if it's necessary), and I forced in a mismatched screw (M6) for safety. I believe the main body has an inch-sized tap. This part doesn't directly bear any weight, so I don't think it's necessary, but please be aware of this.
