Appleton M2-350 Masonry Box

Product Description

The APPLETON M2-350 is a masonry box designed for electrical rough-in applications in concrete block, brick, and other masonry wall construction. It provides a secure, code-compliant enclosure for wiring devices installed in masonry assemblies. Electricians use this box during the rough-in phase before wall finishing, embedding it directly into masonry courses to create a flush, stable device mounting point. The M2-350 is built to withstand the physical demands of masonry installation and the long-term structural loads typical of commercial and residential masonry wall systems.

This masonry box is suited for use in both residential and commercial construction projects where wiring devices such as switches, receptacles, or low-voltage plates must be installed in solid masonry or concrete block walls. It is set during the masonry coursing phase, allowing mortar to fully surround and secure the box before finish work begins. Electricians and electrical contractors working under NEC guidelines will find this box appropriate for standard device-box rough-in in masonry applications.

Key Features

• Designed for direct installation in masonry wall construction including concrete block and brick
• Provides a stable, flush-mounted enclosure for switches, receptacles, and wiring devices
• Built for structural durability under the load and pressure of surrounding masonry
• Supports code-compliant electrical rough-in per NEC requirements

Compatibility

Designed as an OEM-style masonry device box for use in standard masonry and concrete block wall rough-in applications.

Installation Notes

Installation is performed by a licensed electrician during the masonry coursing phase of construction. The box must be set and leveled before mortar cures around it. Ensure all power circuits are de-energized and locked out before making any wiring connections after the wall is complete. Installation should comply with applicable NEC requirements for device boxes in masonry assemblies.
