What Is True Divided Lite (TDL)?

A door glazing configuration in which individual glass panes are separated by actual structural bars or muntins.

True Divided Lite, commonly abbreviated TDL, uses separate pieces of glass divided by actual muntins or bars. The construction creates authentic individual glazing units rather than a visual simulation.

Buying Considerations

Confirm the exact muntin or bar construction, glass thickness, cleaning access, and overall door design. TDL construction can have different cost, weight, and maintenance characteristics from SDL.
