Abstract
An improved detachable nailing flange construction for window and door frames is disclosed. The flange configuration allows the flange to be rotated between collapsed and operative extended positions, while retainably attached to the frame. When collapsed, the flange is protected by the frame for shipment and handling. Means are provided for locking the flange into its extended position and for providing a weathertight seal with the frame. The direction of attachment to the frame can be reversed for selectively adjusting the lateral position at which the flange projects from the frame so as to vary the set-back of the frame relative to the wall in which it is to be installed.
