Leviton SMC Structured Media Enclosure 28 in - Centralized Wiring Hub

Our review of the Leviton SMC Structured Media Enclosure finds it best suited for homeowners and installers who need a tidy, reliable central hub for low-voltage wiring. The enclosure's main selling point is a practical, installer-friendly design: a powder-coated 20 gauge steel housing with a matching 18 gauge cover that conceals drywall imperfections and keeps network, audio, and power modules organized. It is especially useful when a flush or surface mount solution is needed between studs and when modular inserts or small power modules must be accommodated.

Key Features

• Durable steel construction: Powder-coated 20 gauge steel housing with an 18 gauge cover provides a sturdy, long-lasting enclosure that protects wiring and modules.
• Installer-friendly size: The 29.32 in H x 15.62 in W x 3.83 in D footprint fits between standard studs for a neat, centralized wiring location in many homes.
• Multiple knock-outs: Top and bottom knock-outs, including two 2 in knock-outs on top, simplify cable entry and routing for organized installations.
• Power and device mounting: Cut-out in the base lets you mount single or double gang J-boxes and power modules inside the enclosure for tidy power distribution.
• Flush or surface mount: The unit can be recessed or surface-mounted to suit different installation needs, and positive sidewall tabs prevent the housing from falling through studs during installation.
• Concealing cover: The powder-coated white cover has a 3/4 in overlap to hide irregular drywall cuts and improve the finished appearance.

Who It's For

This enclosure is aimed at homeowners upgrading a home's structured wiring for networking, audio, security, or smart-home systems and at professional installers who need a dependable, code-friendly mounting location. The product suits projects where a compact vertical enclosure is preferred and where mounting J-boxes or power modules inside the cabinet is required.

Those who should look elsewhere include projects requiring deep rack equipment or large network switches that need more interior depth or rack space; this model is designed for low-voltage modules and small devices rather than full-size rack gear.

Pros & Cons

Pros

• Well-built steel housing and cover provide a clean, professional appearance and durable protection.

• Positive sidewall tabs and a 3/4 in cover overlap make installation neater and prevent drywall gaps from showing.

Cons

• Some users may find the internal space smaller than expected if they plan to house larger modules or multiple bulky devices.
