Shoulder Boulder/Chest Fly AttachmentBuild boulder shoulders and poppin pecs for that iconic V taper look! Dumbbell shoulder and chest isolations suffer from inconsistent resistance, but the Shoulder Boulders design provides smooth, controlled movement with a superior resistance profile. A standalone rear delt chest fly station takes up a whopping 5 foot x 5 foot footprint (or more), while this rack attachment mounts to your rack to save space. Easily adjust its height on your power rack

Did its job
Got me back onto the water. The mounting holes distances from center to center are less than original equipment. But in a pinch they will do the job.

Easy to use
Style: 6-Speaker
This was a lifesaver. After buying a house, I discovered a huge mess of audio cables wired throughout the place, and this plate made it possible to finally get everything organized.
Quality is decent, not the best, but good for the value.
Super easy to use and connect even old wires to it from the back.

These wall plates look good and work well
Style: 2-Speaker
I used these wall plates for my home theater system. They are easy to install, look good, and accepted my banana plugs perfectly. They make my installation look tidy and I am pleased with the outcome. I have used other Cable Matters products in past and have always been happy with the results.
