Choosing a chain actuator
Check the window type, available space, supply voltage, chain stroke, and push and pull forces. Multiple actuators on one sash require a suitable synchronised solution. Also check the mounting brackets and control requirements.
Use our actuator finder to narrow your selection. Suitable brackets and actuator accessories are available separately.
