Contractor Quality® Half Surface Hinges

Half surface template hinges mount on the surface of the door, and are mortised into the jamb. They work well in applications where the door has a normal hinge bearing surface—the edge—that won’t hold screws well. These S. Parker half-mortise template hinges fit applicable, matching template-guided recesses in the jamb, and have industry standard offset. The 1138 model fits the newer standard offset for 4 1/2" hinges.

Most sizes are available in either brass plated or prime coated finishes to suit most job finishing needs. The hinges are available in plain and ball bearing models.
