The lites used in steel doors are inserted via a lite frame. The frame is held together by screws on the interior side of the door. Lite plugs are inserted into the holes to hide the screws. At times, the screw plugs may get lost or need to be replaced. The number of lite plugs depends on the size of the lite frame. Below is a listing of common lite sizes, and the number and model of the lite plugs.

For any PVC frame, dark colors are not recommended.
