Eaton BB4-23 Box to Stud Bracket Plate 2-1/2 3-1/2 in Studs

Product Description

The EATON BB4-23 is a pre-galvanized steel box-to-stud bracket plate designed to mount electrical boxes securely to wall studs in new or retrofit construction. The bracket accommodates both 2-1/2 inch and 3-1/2 inch stud widths, making it a versatile fastening solution across common framing dimensions. It installs via a screw-on method, allowing electricians to position and secure outlet or junction boxes quickly during rough-in work. At 1 pound and measuring 5.71 inches by 3.50 inches by 4.61 inches, the bracket is compact and easy to handle in tight stud bays.

This bracket is suited for residential and light commercial electrical rough-in applications where a standard electrical box must be anchored to a wood or metal stud. It is typically installed during framing-stage rough-in before drywall, though it can also be used in retrofit scenarios where box repositioning is needed. Electricians and general contractors working on wall outlet, switch, or junction box installations will find this bracket compatible with standard single-gang and multi-gang box configurations.

Installation Notes

Installation is performed by a licensed electrician or qualified contractor during the rough-in phase. Always de-energize the circuit and verify power is off at the panel before working on any associated wiring or box connections. Secure the bracket to the stud face using appropriate fasteners for the stud material, and confirm the electrical box is flush and plumb before finalizing drywall. Follow applicable NEC requirements for box support and mounting when determining fastener type and spacing.
