Need to Double Up on Your Doors? You Have Some Options

Double doors have many uses in a commercial operation, both interior and exterior. Any opening where there’s a need for two-way traffic or where you may need to open up to allow equipment or goods to pass through may require a double door.

A double door entry system may be needed from the front or back entrance to a building, as well as for such interior uses as these:

  • Storage closets
  • Conference rooms
  • Hospital wards
  • Laboratories
  • Warehouses

Types of Double Doors

Double doors may or may not have a vertical mullion down the middle, separating the two panels in the frame. They may also have an active (keyed lock) and an inactive leaf, or two active leaves. An inactive leaf usually can’t be opened until the active leaf is unlocked. A flushbolt may keep it in place until it needs to be opened to allow equipment to pass through. These doors are often used in corridors.

People often wonder if it’s illegal to keep one of two double doors inactive, but it generally isn’t, since you have at least one door that can be used as an exit. Knowing which door is active or inactive is important in the “handing” of a door, which refers to the direction of opening – push or pull. This issue of handing is crucial when installing the frame, doors and hardware. It’s also important for life safety codes involving the path of egress.

You may also have double egress doors used in “cross-corridor” applications. These door leaves swing in opposite directions so that traffic can flow two ways. Both doors may feature an exit device so that either leaf can be used. The doors can’t be described as active or inactive leaves, since there is no mechanical locking hardware on either leaf. Double acting doors, on the other hand, have leaves that swing in both directions, both in and out – like a saloon door. They’re often used in restaurant kitchens.
