The SOUTHWIRE/COLEMAN CABLE MSBST250 is a Smart Box Shark Tooth ceiling electrical box designed for fast, accurate installation of light fixtures and similar loads. The unit features a built-in hole saw that cuts the correct opening size in one pass, eliminating the need for a separate hole saw or paper template. A piercing drill bit tip keeps the box centered on the mark for precise placement. The MSBST250 supports fixtures weighing up to 6 pounds and includes raised mounting rings to accommodate surface mount installations. Electricians and finish trades use this box where speed and hole accuracy are priorities.
The MSBST250 is suited for residential and light commercial ceiling applications where a new-work or retrofit electrical box is required for luminaires and similar fixtures. The mounting hole spacing is designed to accommodate 3/0 and 4/0 fixture canopies. The built-in hole saw and integrated drill bit eliminate extra tooling steps, making it a practical choice for production wiring or repetitive fixture rough-in work. Units are sold in a package quantity of 8, which suits multi-room or multi-unit projects.
Designed for use with 3/0 and 4/0 ceiling fixture canopies in residential and light commercial ceiling box applications supporting loads up to 6 pounds.
Installation is performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize the circuit at the panel and verify with a non-contact voltage tester before beginning work. The built-in drill bit is used to locate and pierce the ceiling surface before the integrated hole saw completes the cutout. Secure the box fully per manufacturer instructions before attaching the fixture.
