Common options include recessed low-voltage pass-through plates (for hiding cables), duplex coax wall plates with coax jacks, blank or mid-way decorative outlet covers, low-voltage mounting brackets, and in-wall accessory boxes that can include a 125-volt duplex power receptacle for combining power and low-voltage cabling.
Coax wall plates commonly use nickel-plated female F-type (F81) connectors. Some product listings specify support up to 3 GHz and reference F81 barrel connectors for termination.
Low-voltage mounting brackets are adjustable to fit a range of wall thicknesses. Listings commonly specify a fit range from about 1/4" to 1" thick for both 1-gang and 3-gang brackets.
Many wall plates and blank covers include matching or color-matched mounting screws. Some coax wall plate packages also include a low-voltage mounting bracket in the box.
Recessed pass-through plates provide a finished opening behind a flat-panel TV or A/V equipment so multiple low-voltage cables can be routed through the wall, keeping cords hidden and organized.
A duplex coax wall plate provides two coax jacks (a dual/coaxial two-jack configuration) and typically includes two F81 barrel connectors for termination.
Typical examples include a 2.9" x 1.9" face opening for a 2-gang recessed plate, a 1-gang mounting bracket opening of about 2.125" x 3.5", and a 3-gang bracket opening around 5.5" x 3.5".
