Most speaker wire wall plates accept banana plugs, spade connectors, and bare speaker wire. Many designs use binding posts that are accessible on both the front and the back of the plate.
Options range from plates designed for 4 speakers up to plates that provide five pairs of binding posts, depending on the model.
Many plates mount to a standard single‑gang opening. Typical plate dimensions are about 4.5 x 2.7 in, with a required wall cutout of roughly 3.74 x 2.33 in. Some brush‑style passthrough plates use a standard 2‑gang bracket opening.
The adjustable mounting brackets are described to fit wall thicknesses from 1/4 in to 1 in.
Brush‑style passthrough plates can accommodate speaker wire, coaxial cable, HDMI, and network/phone (data) cables.
Plate covers and mounting brackets are commonly made from ABS plastic. Binding posts and connectors are typically copper with a gold‑plated finish.
Polarity is identified with color coding and red/black ring labels on the binding posts or thumbscrews for easy recognition.
The binding posts accept bare speaker wire in the 12–18 AWG range and also accommodate banana plugs and spade connectors.
