Rolling door, fire door and security grille accessories for all Cornell products

Mullions

There are multiple mullion options -  corner, fixed and removable.  

Corner Mullions
In situations where a door or shutter spans a corner, these mullions allow guides from two units to be mounted at 90° on a common tube utilizing an over/under coil set up.

Fixed Guide Mullions
In wide openings where multiple units must be installed side-by-side, we can provide fixed guide mullions utilizing minimal guide track space.

Removable Guide Mullions
For extra wide openings that require full access on a limited basis, we can provide multiple doors with removable guide sections.

Please note, all mullion types may not be available on each door.
