An improved mitered joint construction for connecting together mitered ends of two tubular members. One leg of an angled insert having two legs is welded to the interior of one of the tubular members and the other insert leg is trimmed and pressed into the other tubular member to hold the members at a desired angle. The members are then welded together only along the inside edge of the joint. For tubular members having a square cross section, two of the inserts hold the members together at the joint. |
