These are good quality products. They work perfectly with the keystone wall plates also available from Prime Cables. Keep in mind that these are longer than the bare bone wall paper that you do with a crimping tool. So, they are perfect for interior walls because you have more space between the walls. I did it for an exterior wall where there is insulation, so it's a bit awkward.

The are excellent keystones that allow for easy connections without having to use snap in and tool less keystones. They have a very good fit and finish.
