A jamb-alignment bracket.

It is standard on all Marvin-brand doors. It is installed on the head jamb and both jambs of the frame. When coupled with proper leveling of the sill and shimming, this bracket will assist in the squaring of the door frame in the rough opening, and achieving proper frame/panel reveals. It is designed to cut down on installation time and reduce product call backs.

Note: This product is not intended as an anchoring system.
