Abstract: A novel t-astragal for use with double swinging doors such as for french doors is disclosed. The t-astragal includes a cap portion perpendicular to a base portion wherein both the cap and base can be formed from wood such as plywood or plastic. The t-astragal is a moulding that extends the full height of the swinging doors. One side of the base portion is fixably coupled to the free end of one of the swinging doors by nails or screws. The free end of the other swinging doors is able to swing up to and against a shoulder portion formed from the cap and base portions. A metal pipe shaped sleeve having an approximate length of one foot is partially positioned along the longitudinal axis of the t-astragal molding. A bolt slides within the sleeve from a rest position to an extended position, where the extended position locks the attached door to a matching slot in the door frame.
