Here's an unobtrusive HEAVY DUTY DUAL CHAIN 24 volt electric window opener for controlling skylights (or vents, windows, and any other item you would like to move) with a motorized actuator. It can be controlled by a simple switch, or with our optional remote controls. This is a stand-alone unit, not a kit, BY SPECIAL ORDER.
You've seen how handy our window blind and shade systems are, now you can use the same safe, low voltage technology to open and close your skylights. It is simple to adapt this unit to most types of skylights because it does not need to rotate in any way like hinged units do. The dual-chain direct push drive has a 300mm stroke (~12"), the opening/closing force before obstruction is sensed is approximately 60 lbs (28 kg), current consumption is ~2A, protection class is IP32. These units have been stress tested to over 3,000 openings.
If you are planning to use this for a skylight opener, note that you can check the force required to open the skylight by standing on a bathroom scale and pushing up on the skylight with a long broom handle or other suitable pole. If your skylight is heavier than the actuator capacity, you can offset the extra weight with gas shocks, torsion springs or external counterweights.
PLEASE NOTE: Window and skylight openers can be dangerous to children and adults as they normally have a considerable amount of force that is used to draw the window closed and provide security. There is more than enough force to crush fingers of small children and/or cause injury to adults, pets, or other animals.

The linear chain actuator pushes straight out from the housing which lines up unobtrusively with your skylight frame, fastened in place with mounting screws. Attach the end of the chain actuator to the skylight frame with screws and you're done!
Use it to control the motion of anything you want, including skylights, windows, greenhouse vents, etc.
Use with our wired wall switch, or use our radio remote controls, or interface it to a home automation system using our optional ZWAVE group controller..
Care should be exercised when these units are installed where adults or children could get fingers caught in a closing window - serious injury could result. Use of insect screens can help eliminate this possibility.
