Products - Combination Door Dimensions
We at The Maiman Company believe in the importance of flexibility, allowing you to choose the door you want. The charts below set out our minimum dimensions for our combination doors as well as the maximum dimensions that will secure a UL- or Warnock Hersey-sponsored fire rating. In addition, we can usually construct doors that surpass the below dimensions and give them Construction Label Only (CLO) tags.
NOTE: combination doors with true divided lights are not available in 45-60-min fire ratings. A similar look is achieved using light kits and rails/mullions; accordingly, a particular component such as a light kit may change or add the requirements listed below. If there are questions, contact our factory at 417-862-0681.
