The ORBIT INDUSTRIES 5BC-MKO is a flat, square switch box cover designed to close out 4-11/16 inch square electrical boxes. Constructed from galvanized steel, it provides durable protection and a finished appearance for flush-mounted box installations. The cover features an MKO knockout configuration, giving electricians a pre-punched opening sized for standard device or conduit applications. This type of cover is a routine component in commercial and residential rough-in work, installed by licensed electricians during box finishing or device rough-in.
This cover fits 4-11/16 inch square electrical boxes in both new construction and retrofit applications. The flat profile suits installations where a flush, low-profile finish is required at the box face. The MKO configuration is commonly used in conduit or device mounting applications in commercial electrical work, including panel extensions, junction finishing, and device rough-in across light commercial and residential job sites.
Designed as an OEM-style replacement or standard fit cover for 4-11/16 inch square electrical switch boxes requiring a flat galvanized steel cover with an MKO knockout.
Installation is performed by a licensed electrician. De-energize the circuit and verify zero voltage at the box before installing or removing any cover. Secure the cover to the box using the appropriate machine screws for the box type. Work must comply with applicable NEC requirements for box fill, cover securement, and box accessibility.
