Metallic Trunking Single Knockout 200*50

A single knockout 200×50 is an electrical junction or switch box with dimensions 200 mm × 50 mm, designed to house one electrical device such as a switch or socket. The term “single knockout” refers to a pre-scored opening that can be removed to allow a single conduit or cable entry, making wiring neat and convenient. These boxes are typically made of PVC or metal, provide protection for wiring, and are used in residential, commercial, or industrial installations for surface-mounted or recessed electrical connections.
