ABSTRACT:
The present invention corrects sash sag in casement windows by implementing an adjustable hinge. The adjustable hinge includes a sash arm, a support arm, a retaining clip and an adjustment mechanism. The adjustment mechanism serves a twofold purpose. First, it allows one to adjust the hinge for sash sag, and it also secures the support arm to the track of the adjustment hinge. The adjustment mechanism includes a threaded support post and a threaded member. The threaded support post has a circumferential groove which is used to receive the arms of a retaining clip. The sash arm is mounted to the track of the adjustable hinge via a shoe block. The sash arm has a protrusion located on its bottom surface. The protrusion serves as a movement restrictor.
