Stile and Rail Combination Doors Maiman Our combination doors offer tremendous flexibility and style. These doors are available as true divided lites up to 20-minute fire ratings. We can also use custom elements such as metal lite kits to provide the same look for higher rated doors. Maiman offers several standard combination door options. In addition, we can also make custom combination doors according to your specifications that offer you more flexibility. * Note: 45, 60 and 90-minute doors require metal or veneer wrapped metal lite kits (not true-divided lite) which will decrease the illustrated division of 1 in. to 0.75 in. 60 and 90-minute doors with more than 100 sq. in. clear view area of glazing will carry a temperature rise rating in excess of 650 degrees Farenheit. *The top edge of the bottom rail must be a minimum of 10" above finished floor to comply with ADA requirements.
