ABS plastic is nonmetallic and wireless transparent, so it helps radio signals pass through the enclosure with less attenuation and reflection than metal. This allows devices such as routers, access points, and streaming equipment to operate inside the box while supporting cleaner wireless connectivity.

Choose a 20-inch ABS plastic box for smaller installations, a 30-inch box for routers, modems, switches, and power accessories in many residential systems, or a 42-inch box when you need room for several modules and larger equipment. Before selecting a size, account for device dimensions, cable routing, ventilation, and potential system expansion, then confirm that the enclosure’s mounting options and cover depth fit the installation.

When installing an ABS plastic box, confirm the available wall or ceiling space, choose recessed or surface mounting as appropriate, and account for stud placement, drywall depth, trim rings, covers, and access for servicing. Plan cable routing and knockouts before mounting, leave room for connected equipment and ventilation, and use the box’s mounting points or retrofit hardware to secure it in the selected location.

Mounting grids provide flexible attachment points for routers, switches, power strips, and other equipment, while knockouts simplify cable routing and power connections. Covers add protection and a finished appearance, and vented designs help release heat, so leave room for the cover, cable bends, and airflow during installation.
