QualGear Pro-AV QG-KIT-CA-3IN-B Single Joist Ceiling Adapter, 3" 1.5" Projector Mount Kit Accessory, Black

I needed a mount with a specific drop down in length and this was next to the only thing available with a swappable pipe length system that looked reliable. The next thing I was going to get if this didn't work was a Peerless mount, which was going to cost well into the $150+ range after needing all the bells and whistles. Glad I decided to try this mount out.I was worried that this would not fit my BenQ HT2050a but decided to look at the measurements and it seemed like this could fit pretty much close to anything with a little tinkering. Well I'm happy to report that this does in fact fit the BenQ HT2050 / HT2050a. See my first image attached on how I was able to connect all three mounting points. I was able to point the mount in the direction of the screen too (there's arrows that point to the direction it should face). I only needed three arms, so I took off the fourth too. The arm that is sticking out in front does not interfere with the image on the screen as well.The current measurements that I got with the default 3 inch included pipe (which actually measures to something like 4.75 inches with the threads) from the ceiling to center of the lens was 10.5 inches. I needed it to sit around 11.5" - 12". Luckily this mount is compatible with the standard 1.5" NPT threaded pipes in the plumbing aisle of home depot. So I ended up buying a 6" NPT 1.5" threaded pipe for I think like $6/$7. With this swapped pipe out, now it will sit for me at 11.75" -- perfect.Another thing that I was worried about was not having the pipe lined up with one of my joists since they run longways in the room and not side to side. In the directions they have you use the center holes only for mounting to a wood joist and the other four for cement installation. I needed to have it offset from the joist so I used one of the corner holes in a wood joist and the opposite corner hole with a toggle bolt that holds up to 95 lbs. Seems pretty sturdy to me. That one screw in the joist should be enough to hold it to be honest.It took me a couple of hours after work to measure, prep, figure out the mounting situation on the projector, run to home depot, measure five more times, and then decide on a spot making sure I was going into a joist, and finally installing it. Lot of pressure trying to decide where you want it to sit. If I need to move it down the road I'll probably install a painted piece of plywood mounted to the joists for flexibility sake.So happy it's up now and ready to continue working on the room / screen. For what you get I would definitely rate it five stars. Simple and straightforward and useful for rotation and flexibility of length with the 1.5" NPT threads. My situation, experience, mounting and length requirements is certainly irrelevant of the product.

This is a heavy duty mount. The mounting plate has six mounting holes. Two in the middle for a 3/8" bolt and four in the corners for 1/4" bolts.This mount is generally meant for larger/heavier projectors and meant to be screwed directly into a ceiling joist or suitable blocking. I am using this with a 6-inch extension pipe and a LG HU810PW projector and the mount/projector assembly weight right at 30 pounds as weighed on a postage scale. You cannot mount this kind of weight into sheetrock, no matter if you use toggle bolts or anything else. The mount needs to go into a block of wood or a stud with suitably beefy mounting screws/bolts.In my case, I installed 2x6 blocking between two studs and through-bolted the mount with 3/8" bolts. It's not going anywhere. Just be advised if you're looking at a heavy duty mount like this, you're probably in the same weight situation as I am, so plan accordingly.I read a bunch of comments that the extension tubes/pipes are not NPT. I can't comment on that as I used the manufacturer's 6" extension. Seen enough of these made in China mounts to know that when they try to implement US standards like NPT, sometimes they succeed, other times not so much. Just spend the extra few bucks to the the manufacturer's extension tube vs. a pipe from the big box store and have a guaranteed fit.

Ceiling mounted a Sony 1100 projector weighing 44+ pounds. Yes, as with any heavy projector, you must be certain your ceiling will support the weight and as I had to do, add reinforcement to be certain. No big deal, just something you need to be aware of. This mount has a 70 pound capacity so it gave me great headroom for the projector. Adjustments are a little of a pain as you will need to loosen three Allen head screws on each side (6 total) for both X and Y axis adjustments. This is a little cumbersome but once accomplished, it is rock solid. Again, not a deal breaker as it just requires a little patience. The quick release feature is robust but you do have to be cautious when attaching the projector as one slip could be bad. I man handled the 44 pound projector by myself but would highly recommend using at least one other person for heavy projectors so they can stabilize the projector while you tighten the screws. I have added a safety cable for my own peace of mind but it is not necessary. Fit and finish is great. All components (screws, washers, Allen wrenches) are bagged separately and very well organized. Assembly is simple and straight forward. The Sony 1100 has only three mounting holes and although this mount would work as is after removing one mount arm, I wanted the pipe to be better centered on the projector and closer to the rear hole so I fabricated an accessory out of one inch aluminum angle that spanned two of the mount holes after removal of the two arms impacted. That left two arms to attach to the most forward two mount holes and resulted in better centering the main pipe much closer to the projectors center of gravity. I would highly recommend this mount if the weight of your projector warrants it. Fit and finish is excellent.

Good product holds my BENQ LK936ST well. The only “issue” is there are so many adjustments on this mount it makes locking it into place difficult if you are striving for perfection.
