RiteAV Speaker Spring Clip Keystone Jacks are the same on the front and back, so you can connect your wire to them in no time. Simply push in the color-coded, spring loaded buttons and insert the wire on both sides of the plate the same way. No tools are required. They're literally push and play, so the installation process is simplified, while the sound quality is not compromised. The couplers provide clear, crisp Hi-Fi Sound for Home Theater and Audio Systems alike. They're universally designed to easily fit standard-sized brand name keystone blank wall plates and fit seamlessly into all RiteAV Blank Wall Plates as well. RiteAV Keystone Couplers are removable to allow for easy upgrades or plate re-configurations in the future. The sturdy construction of the couplers ensures a long service life and a simple, affordable way to keep your cables hidden. This discreet solution enables you to route your cabling through the walls and results in a clean, professional look behind wall mounted televisions, monitors, projectors and entertainment centers in both residential (home theater) and commercial (classroom, boardroom, factory floor, recording studio, etc.) settings. We offer a variety of couplers in an assortment of colors that all match our Blank Wall Plates to suit all of your A/V requirements. This listing is for a 12 Pack.
