Keyed Removable Mullions
Detex Keyed Removable Mullions
A keyed removable mullion is a center post for a pair of doors that can be removed with a key when the full opening is needed. The Detex 90KR is listed in 7, 8 and 10 ft lengths, and the F90KR is the fire-rated keyed removable mullion, such as the 7 ft F90KR-7.
Pair a mullion with rim exit devices from the Value Series or Advantex lines. Browse the full Detex catalog, or Contact our team with your opening height.
