FAQ Knowledge Articles

In the field, there are several ways to determine whether you have a Tilt Sash Lock or a Non-Tilt Sash Lock.

First, turn the sash lock to the 135 degrees position. If the button popped up, you have a Tilt Sash Lock. If it doesn’t pop up, it is a Non-Tilt Sash Lock.

Second, if there is a performance bracket on the frame, then it is a Non-Tilt Sash Lock. To determine if your window has a performance bracket, raise the bottom sash all the way up. If there is not a performance bracket on the frame, it could still be a Tilt Sash Lock if the bottom sash operation has not been limited .

Does the window have a bottom sash limiter? If it does, then it is a Non-Tilt Sash Lock. The Sash Limiter will be approximately four inches (6’ and 8”positions are also available)  up from the check rail on side of the jamb. If it doesn’t have a performance bracket on the frame or a bottom sash limiter then, it is a Tilt Sash Lock.
