How to Measure for Your Window Locks

Occasionally, window locks can interfere with your window grille pattern. In events where that occurs, we will notch the window grille to fit around the lock keeper. Please follow the below steps to measure for the placement and size of the lock keeper.

    1. Measure from the left edge of the visible glass to the center of each lock.
    2. Measure the height of the lock from the tallest point to its resting place on the sash.
    3. Measure the lock width to the outermost points.
