A junction box for receiving electrical cables and for housing electrical components has a base member and a lid member positionable over the base member to form an enclosure. The lid and base members are hinged on one side. On the side opposite the hinges is a clasp assembly via which a user may lock and unlock the base from the lid by two independent locking mechanisms. Lower and upper concentric flanges slidably engage cable conduits. Knock-out elements may be removed from within the concentric flanges to form apertures through which cables may pass from an engaged cable conduit into the enclosure. A mounting flange may be used to install the junction box within a recess of a building, between wall layers. A skirt flange may project from the junction box in the exterior direction past the external wall layer to convey moisture away from the building recess.
