Metallic Trunking 150*50 Single Knockout

A single knockout 150×50 refers to a single-gang electrical box or wall plate with dimensions 150 mm × 50 mm, designed to house one electrical device (like a switch or socket). The term “knockout” indicates a pre-scored area that can be removed to allow conduit or cable entry, making wiring easier. These boxes are typically made from PVC or metal, providing protection for wiring and a secure mounting point for electrical fixtures in residential or commercial installations. They are widely used in surface-mounted or recessed wiring setups.
