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 seal is achieved by a pair of silicon fins. Two RP71Si seals are installed on to the one door stile which allows space for a latch between the two seals.
The legs of the seals can be checked out to accommodate the latch bolt front plate providing a continuous seal.
Note: Minimum door thickness subject to centre latch and dimensions of morticed door bottom seals.
