Choose the gang size based on the number of low-voltage inserts or devices the wall plate must hold, such as one for single-gang, two for double-gang, or three and four for larger installations. Match the bracket to the planned wall plate and available wall space, and confirm that its mounting style suits the project, such as retrofit or new construction.

Low-voltage mounting brackets accommodate wall thicknesses from one-quarter inch to one inch for many retrofit applications, while some fast-install models adjust from one-quarter inch to one and one-half inches. New-construction brackets are also available for one-half-inch or five-eighths-inch drywall.

Many low-voltage mounting brackets are compatible with standard inserts and wall plates, especially single-gang designs. Check the bracket’s gang size and installation type to confirm it matches the insert or wall plate used for the project.

Compare whether the bracket is designed for retrofit or new construction, its gang size, wall-thickness range, mounting method, and whether it supports vertical or horizontal installation. Also consider features such as a built-in cutout template, hole-saw installation, cable tie loop, compatibility with standard low-voltage inserts and wall plates, and support for common drywall thicknesses.
