Abstract
A mild steel outlet box is stamped from flat sheet stock into a base and a cover that fit together with an interference fit that avoids the need for threaded fasteners. The base has circular knock-outs in the side and end walls, each of which is aligned with a knock-out slot in the bottom wall to allow an electrical metal tube (EMT) to be secured to the box without the usual offset bend. Each such knock-out opening also has a set screw threadably received in an integrally formed land aligned with the knock-out opening to secure the tubing to the base. An electrical device can be pushed into place without threading its fasteners. Hardened steel clips are mounted to the base for slidably receiving such fasteners so they must be unthreaded for removal. Each clip has a V-shape with the apex of the V defining a slotted opening that so receives the threaded fastener.
