A fixed mullion
cannot be moved when both sashes are open.
The French Casement mullion
is fixed to the leading edge of the Sash
2. Once Sash 1 has been opened, the mullion can be disconnected
and Sash 2 subsequently opened. The mullion will move with the sash
providing a clear opening for both sashes.
The mullion is disconnected by the mid-positioned flush bolt (1) or
the barrel bolt (2) and Sash 2 is opened. The French casement mullion
must be re-engaged before closing Sash 1.
The removable mullion
stays in the opening when the sashes are
opened. In the event of fire it can be entirely removed by opening both
sashes, loosening the barrel bolt (3) and push out the mullion.
