Astragal boot for a double door set

摘要

An astragal boot provides a substantially weatherproof seal at a lower end of a vertically elongated astragal installed on the free side edge or stile of a semi-active door in a double door entry set or the like. The astragal boot includes at least one and preferably multiple compliant fins for engaging an underlying threshold, when the semi-active door is in a closed position, to provide an effective barrier against penetration of wind and water. In the preferred form, the astragal boot further supports and retains adjacent ends of complaint weatherstripping mounted on the astragal and/or the bottom edge of the door. The astragal boot may be provided in a non-handed configuration for reversible mounting on a left-hand or right-hand installed semi-active door.
