Features

• Fabricated from premium-grade galvanized steel with a fully welded design, the MBD2K offers exceptional structural integrity that withstands the immense pressure of curing concrete and heavy masonry units. This heavy-duty build guarantees your electrical box maintains its shape and perfect alignment, preventing costly structural failures and ensuring a smooth, flush finish on every rough-in.
• Featuring an expansive 42 cubic inch capacity, this 2-gang masonry box delivers ample internal room for deeper smart switches, heavy-duty commercial receptacles, and dense wiring configurations. This generous depth eliminates crowded box conditions, significantly reducing the risk of wire pinching and insulation damage while simplifying code-compliant installations.
• Outfitted with multiple 1/2-inch and 3/4-inch concentric combination knockouts on the sides, bottom, and ends plus a larger 1/2, 3/4, and 1-inch combination breakout on the ends this box adapts effortlessly to various EMT and rigid conduit routes. This extensive layout eliminates the need for field modifications, allowing commercial electricians to quickly punch out the required access points and complete pipe runs on tight schedules.
• Designed with a pre-tapped, raised ground screw area, this masonry box streamlines the bonding process by offering easy tool access even when embedded in a wall. This thoughtful feature saves valuable installation time during the trimming phase and ensures a dependable, low-resistance path to ground that aligns perfectly with safety mandates
