About Square Type 38

This device helps users recognizing if the light inside a room is on from outside. The indicator lens can be easily attached to the door by pushing it into the hole (prior drilling needed). The thin ring on both ends is designed with a wider surface to hide the mark of the drilled hole on the door.
This product has a sharp design on both edges to enhances the look of the door. This square type is available in two exclusive finishes to complement any doors color.
