  • Installation and Technical Information


Heavy Duty Surface Vertical Rod Device - (suits doors <915mm  x <2134mm) Anodized Aluminium.

The Quiet One®

A fluid dampener decelerates the touch bar on its return stroke and eliminates most noise associated with exit device operations. Furnished on all 33A Series Exit Devices

In accordance with BS EN 1125: 2008 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.
