A medium temperature smoke astragal seal designed for plain or rebated meeting stiles of timber double doors where a centre latch bolt may be required or, where both doors are active.

The legs of the seals can be checked out to accommodate the latch bolt front plate providing a continuous seal.

Location: Meeting stiles of double butt hinged and centre pivot double acting doors.

Min/Max Gap: 3 mm to 5 mm.
