Upgraded an existing RR Multi Cable set up to add HDMI. Had to replace the WireMold wall box to capture the 2 gang plate but it worked perfectly. My existing run is an old "yellow" cable with an "orange" adapter on it at the user end so I should have gotten an extra deep WireMold. Made it work by adding a second box above the first to enclose the extra long connection.
Added 50' of RR Fiber Optic with a powered receiver at the projector. Even with another 50' of cable between a laptop and the wall connection it works flawlessly!
