Automatic Door and Hardware has the best selection of glass lites for commercial steel and wood doors. Glass lites are easy to install and can bring light through the door to brighten a room. They can also act as a visible window so pedestrians can see inside or outside of the door way. We offer fire rated glass lite kits as well as non fire rated models, depending on your needs. Glass lite kits come in tempered clear glass, pyran, or wire mesh. Shop today and get free shipping on all commercial door glass lite kits.
