Description
Features
- The integrated MSB metal stud bracket is specifically engineered for flawless attachment to both 2--3/8 in. and 3--5/8 in. steel stud sizes, featuring a precise 0.4375 in. bracket setback for consistent flush alignment. This heavy-duty mounting system eliminates the need for separate tracking clips or hardware, significantly speeding up high-volume commercial installations while ensuring a rock-solid foundation for ceiling or wall fixtures.
- Designed with a standard 1--1/2 in. depth and a total volume of 15 cu. in., this 4-inch octagonal box provides the structural room needed to comfortably house device connections without dangerous wire crowding. It is optimized to comfortably fit standard Non-Metallic Sheathed (NMD) wiring up to 14/2 or 8/3 configurations, keeping you fully compliant with modern electrical code requirements.
- Equipped with six highly versatile knockouts, the box features two 1/2 in. entry points alongside four 1/2--3/4 in. concentric combination knockouts distributed across the bottom and ends. This layout allows for seamless transitions between varying conduit sizes and prevents the field-delays caused by incompatible wiring paths during multi-system commercial build-outs.
- Built with advanced self-tapping, combination-head screws, the assembly virtually eliminates field stripping and cross-threading issues during high-torque power driving. This robust fastener design ensures faster, tighter connections that withstand the persistent vibrational stresses common to active industrial and residential environments.
