The Mortise for Pitcher Handle Sets is a carefully crafted and specialized door preparation designed to accommodate pitcher-style door handles. This mortise, often carved or routed into the edge of the door, serves as a precise housing for the pitcher handle mechanism.


Pitcher handles are characterized by their unique design, resembling a pitcher or jug, and are often used for doors with a vintage or classic aesthetic. The corresponding mortise ensures a secure and precise fit for the handle, allowing for smooth and reliable operation.


Crafted with precision and attention to detail, the Mortise for Pitcher Handle Sets is an essential component in achieving the desired look and functionality for doors adorned with pitcher-style handles. It plays a crucial role in ensuring that the handle sits flush with the door surface, contributing to both the aesthetics and seamless operation of the overall door ensemble.


The door can be locked 3 ways and all three lock the doorknob on the outside. It is only unlocked by pushing the buttons. This lock uses a jointed spindle so that the inside doorknob never locks.


These are the 3 ways to lock the door:

-key from outside locks knob and throws deadbolt

-turn piece from inside locks the knob and throws deadbolt

-push buttons (only locks the doorknob, does not throw the deadbolt); used when leaving.  No key is needed.

Mortise for Pitcher Handle Sets

  • Handing

    Handing indicates which side of the door set will go.  Standing inside with the door opening to you, if the set is on the left, it is a left handed door.

  • Backset

    Backset indicates where the set will be centered on the stile (vertical board at the side of the door).  For stiles 5" wide or less, select the 2 1/2" backset; for doors with wider stiles, select the 2 3/4" backset.  If your stile is narrow, let us know and we can supply the correct backset.
