Include an HDMI connection in your custom audio/video wall plate using the HDMI Keystone Jack from Monoprice! This keystone jack is designed to fit any standard keystone wall plate. It features a gold-plated female connector on each end, allowing you run an HDMI cable through the wall. This keystone has no effect on the signal and therefore supports all High Speed HDMI features, including 3D video, 4K video, and high-definition multichannel compressed audio.
