Folding arm actuator especially designed for large dome lights and roof exits. Push force of 550N. and a 1200mm. stroke.
Suitable for roof lightdomes and roofexits where a large opening stroke is required. (>90 degrees possible)

Installation depth only 165mm.

The internal mechanism (gears etc.) is made of high grade steel, the housing from extruded aluminium and has a stainless steel arm.

I.a. by the use of these high quality materials is the folding arm actuator very reliable. The lifetime is tested > 20,000 cycles.
In addition, the actuator is tested at 300ºC for 30 minutes, and the maximum opening time ><60 sec.(tested acc.EN12101/2).
This makes the folding arm actuator also suitable for SHEV installations.

Comes standard with "Tandem-function". Up to 4 actuators can be connected in parallel.
Due the exact speed of the folding arm actuators a synchro function is unnecessary.

Mounting brackets need to be ordered separately.
Special profile depending brackets are available as an option (e.g. Schüco, Wicona, Raico).
On request we can provide custom made brackets for your projects.
