Blank Hinge

A blank hinge, butt hinge, or mortise hinge is often seen on doors. This kind of hinge is formed by two identical metal wings that are joined together by the middle pin and barrel system. One of the hinge’s wings is attached or recessed onto the door, while the other wing is connected to the jamb.

The butt hinge is the most frequently used hinge on different kinds of doors and windows, which you’ll surely see in every home. There are types of heavy-duty butt hinges, such as Ball-bearing butt hinges (for heavy doors) and Lift-joint butt hinges (removing the hinge pin makes it effortless to detach the door from the frame).
