Recommendations for Installing & Fixing

In accordance with BS EN 1125:1997 Annexe A (informative) the device should be installed with the touch bar normally at a height between 900mm and 1100mm from the finished floor level when the door is in the secure position. Where it is known that the majority of the occupants of the premises will be young children, it is acceptable to reduce the fixing height accordingly.

Strikes for 9857/9957 Surface Mounted Vertical Rod Devices

299 Top & Middle Roller Strike with 21mm projection (top), used with conventional frames where a reveal >32mm exists, (middle) used with conventional frames where the door stile width >121mm permits the necessary back set.

248L-4 Bottom Strike for use with flat top thresholds. Since the strike projects by 10mm care should be taken to ensure installation does not pose a trip hazard

304L Optional Bottom Strike for use where a mortice installation is desired.

Both the 248L-4 & 304L Bottom Strikes are supplied as standard with all surface mounted vertical rod devices.
