How to Measure for Simulated Divided Lite (SDL) Window Grilles

Measurements must be taken on both the inside and the outside of the glass.

To measure Daylight Opening (DLO), measure the visible glass, from stop to stop.

To measure the Tip-to-Tip dimension, measure the longest part of the grille on the top of the profile (the portion that faces outward from the glass).

To measure the Underneath dimension, measure the shortest part of the grille bar on the bottom of the profile (the portion that touches the glass).
