TAB-LOC Lets one man assemble a steel door frame in 10 minutes. The secret is the exclusive, patented locking tabs found only from National. These built-in fasteners are pre-punched into the frame members. Just bend the tabs down into matching slots for a square, tight, permanent steel door frame. Unlike any other door frame, you don't even need a level area for assembly. Once you're familar with TAB-LOC, 10 minutes is all it takes to get a frame ready to attach the siding. In fact, the door can be comleted and hung in under an hour to previously installed rail.
