Include the Tramontina type LR 4-inch fixed conduit box with NPT thread, cover and electrostatic powder painting in your electrical projects and ensure high quality and versatility. Made of aluminum, it has high mechanical strength and corrosion resistance, and is ideal for residential, commercial or industrial electrical installations, especially exposed, when there is no intention to break the wall in order to embed the wiring. For installation outdoors or where there may be non-flammable liquids, dust, gas and vapors, it comes with an IP54 gasket and has tapered thread that ensures a perfect seal!
