Leviton 42 in SMC Box and Flushment Cover - Durable Network Enclosure

In this review the Leviton 42 in SMC Box and Flushment Cover is assessed as a practical structured media enclosure for single family homes and light commercial use; its biggest selling point is the combination of durable steel construction and installation-friendly features that make it a straightforward place to centralize networking and low-voltage systems. The reviewer finds the unit best when you need a neat, recessed or surface-mounted cabinet that accepts standard single and double gang J-boxes and simplifies cable entry with multiple knock-outs.

Key Features

• Powder-coated steel construction: Heavy-gauge 20 and 18 gauge steel provides a sturdy enclosure and cover that resists wear during installation and everyday use.
• Multiple knock-outs: Top and bottom knock-outs, including two 2 in knock-outs on top, allow flexible cable entry and routing for modems, routers, and other devices.
• Flush or surface mounting: The enclosure can be installed recessed between studs or mounted on the surface to fit different installation needs.
• Cut-out for J-boxes: A cut-out in the base accepts single and double gang J-boxes and power modules so power and low-voltage terminations sit neatly inside the cabinet.
• Positive tabs for installation: Tabs on the housing sidewalls help prevent the enclosure from falling through studs while securing it in place during rough-in and final mounting.

Who It's For

The Leviton 42 in SMC is ideal for homeowners, small contractors, and integrators who need a central point for DSL or cable modems, routers, VoIP gear, distributed audio, or security system components. Its size and built-in knock-outs make it suitable when multiple devices and cable runs must be organized in a single location.

It is less appropriate for large commercial installations that require racks or full 19 in mounting, or for users who need extensive internal shelving or active cooling; those buyers should consider larger enclosures or rack systems designed for equipment-heavy deployments.
