This Offset Swing Clear Hinge from Adaptive Access is a good option for people who need to widen a door opening without widening the framed area. The hinge can add about 2" additional usable space in the door opening.

The heavy duty swing clear offset hinge is quick and easy to install and uses the existing holes and screws. The hinge measures 2" x 3-1/2" with a decorative, long lasting brass finish. (2" wide to wrap the trim).
