<p>The joint box is fitted between two lengths of conduit which are required to join together at a right angle. The box provides a base to accommodate the conduit ends, and has an internal support. This provides fittings for attachment of a cover, fitting over the ends of the two abutting conduit lengths. The flat angle section is inserted to form a joint between the bases of two sections of conduit. It includes a base section (110) with a base panel (111) and two walls (114, 115) perpendicular to the base and to each other. The base section receives the adjacent ends of two perpendicular sections of conduit. A support element (120) is fitted inside the base section. This provides fittings (124,125) to receive one part of a cover element (130) which fits over the joint. Further supports (118) are provided on the inside of the upright walls of the joint, enabling the attachment of the cover (130).</p> |
