F521
Fermod Latch & Inside Release, with Lock.
For Hinged rebated or overlapping doors from 27mm to 213mm offset.
Strikes & Shims are sold separately depending on your door requirements.
CRH & All manufacturers highly recommend that all internal safety release mechanisms fitted to doors are checked at least 3 times weekly to ensure they are functioning correctly.
The F521 Fastener kit is supplied with both the External & Internal Fastener. The customer will however have to choose which Strike they require dependant on the Offset of the Door. The Offset measurement is the distance from the frame or wall panel that the Strike will be attached to, out to the face of the door panel. Once you have this measurement you can choose from one of the Fermod Adjustable Strikes, there is also a stackable 17mm Strike Packer if you require it for larger offsets.
