ABSTRACT:
An improved astragal assembly for use with a double door installation includes an astragal strip secured along the vertical edge of the inactive door. A lock block is slidably disposed in at least one end of said astragal strip and can be moved between an extended position for securing the door and a retracted position for freeing the door. The lock block has a projecting bolt receivable in a receptacle in the door frame when the lock block is slid to its extended position. A gasket is secured to the end of the lock block and the bolt passes through an opening in the gasket. The gasket engages and seals against the door frame when the lock block is in its extended position. Gaskets are also provided on the sides of the lock block for engaging and sealing against the doors of the double door installation. When the doors are closed and secured in place, the lock block and gasket assembly prevents drafts from flowing under the door installation beneath the astragal thereof.
