RiteAV Female to Female Banana Jack Keystone Couplers are the same on the front and back, so you can connect your Speaker Wire to them in no time. Theyre color-coded red and black on the front and back side of the coupler, so that polarity can be easily identified. Simply plug your terminated wire into the front and back the same way. No tools are required. If youre using bare wire, you may unscrew the caps and use the binding posts to terminate bare wire. The Gold Plated Binding Post provides a reliable connection providing superior conductivity and sharp audio. The couplers are universally designed to easily fit standard-sized brand name keystone blank wall plates and fit seamlessly into all RiteAV Blank Wall Plates as well. Our Banana Jack Keystone Couplers can also be used in surface mount boxes and patch panels that have standard-sized openings. RiteAV Keystone Couplers are removable to allow for easy upgrades or plate re-configurations in the future. The sturdy construction of our couplers ensure a long service life and a simple, affordable way to keep your cables hidden. They also provide a neat, convenient way to extend cables that are already in place, without the need for relocating them. This discreet solution enables you to route your wiring 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. Please note that Speaker Wire is not included with the product. It is referenced as an item that the Banana Jacks may be used with. Our 2 Pack includes 2 units (1 x Banana Keystone Coupler with a Black Ring and 1 x Banana Keystone Coupler with a Red Ring). The 2 Pack is designed for use with one speaker, so please purchase additional packs if your setup includes multiple speakers.
