Some fiberglass doors include a lite, or piece of glass, that is inserted into the door. This piece of glass is surrounded by a lite frame. At times, this frame may need to be removed and replaced.
In this video, Therma-Tru provides a comprehensive, step-by-step, tutorial explaining how to replace a lite frame in a door unit. Follow the recommended installation guide or have a contractor install the replacement lite frame. Replacing a lite frame requires using tools that are not provided by Therma-Tru, and may be difficult to locate. Feel free to contact Therma-Tru with any questions or concerns about maintaining a door unit.
