Jumbl SINSB7W ProGrip Ultra Stainless Steel Speaker Wall Mount Bracket White, Pair of 2 - Thread Size: 1/4-20 - Holds up to 10 Lbs

I'm not sure how this little item takes on so much force, but screw the base into a stud and then screw the quarter-20 bolt at the other end of the ball into your speaker. Then you insert the ball into the jaws and tighten it. Some have reported problems but you can solve them with a long and strong Allen wrench screwdriver. Get some muscle into it and they work great!

These are great! They work perfect with my roku speakers!

Bought used. Received the wrong color. Ordered white but got black. However, it's fine. The mounts are actually really good for our polk surround speakers. If I got the white color it would've been 5 stars, though.

Used both to hold a Polk Monitor XT35 Center Channel speaker weighing 14lbs. It needed to be above the tv and angled down. Screwed a white melamine MDF board to the wall's studs and then drill holes in it to use 1/4-20 Hex Drive Wood inserts to attach these mounts to the board. I used the same inserts on the speaker since it only had keyhole holders. You have to be very accurate taking measurements and leveling. Bottom line, I was able to angle the speaker to my desire and the brackets handle the weight perfectly. A reviewer said that one of these wasn't holding his bookshelf speaker that weighs 10 lbs, most likely because it has too much leverage, the speaker is too deep and these were not designed for a speaker that big, regardless of its weight. My speaker is heavy but it is slim and not too deep, plus I am using both brackets; obviously I can only move the speaker in one axis, but that is all I needed. Also, the hex wrench provided is not convenient, it'll do the job, but it'll frustrate you. I used a hex bit socket and a ratchet wrench, so I could quickly tighten each screw while holding the speaker in the desired position.

Compre 3 paquetes "usados como nuevos" y venían en perfecto estado incluso 1 paquete parecía nuevo.La calidad es robusta, duradera y de calidad parece que durará para toda la vida.

I had some nice speakers on shelves. When I used these to mount the rear speakers, I noticed a remarkable improvement in sound, so I immediately ordered these for the front ones as well. It's a vast difference in sound quality!!!

These clamps were the largest I could find. One speaker position needed to be extended past my patio door blinds which added excessive stress on the clamp and it wouldn’t hold position. I also supported the speakers with a hook and wire from the ceiling to stop gravity weight pressure on the ball clamp. I used a coupling to match the 3/8-16 threads in my speaker mounts. The 1/4-20” ball clamp threads will bend or break at exit point of ball clamp if speakers are heavier than recommended and not good if you need to extend past the thread lengths provided . 3/8-24 minimum size fine threads and 1-1/2” ball clamp minimum. The clamp thread needs to be 7/16” fine thread minimum with a full size jam nut for more holding power.All threads need to be fine threads on ball clamps and inserted metal speaker mount threads. Fine threads have more holding power.

Worked very well. Durable, easy to install. Great price and size.
