Identify tilt latch for replacement

Hello there. The only way to identify these internal tilt latches is to remove one of the surface levers and show us the prongs underneath. The length of the prongs, and the distance between them, will identify the surface lever as well as the corresponding internal tilt latch. See our selection of finger levers here to get an idea of what I mean. You should know from the start that oftentimes there is no available replacement for these internal latch assemblies, since many are no longer made. As that may be the case with yours, consider converting to surface-mount tilt latches like our 26-228 and 26-229, or 26-193 and 26-194. The video below shows how to do this.
