RollerTrol™ Skylight and Window Openers: Our window and skylight openers are very unobtrusive, blending well with your decor as there are no exposed rods or levers. The chain emerges at right angles from the housing to form a semi-rigid arm that will open a window or skylight. These units also work with our blind and shade motor remotes and automation systems. We have interfaces available for almost any type of automation protocol, not just our own preferred BroadLink® RF-IR blaster controller hub (with RF and IR learning capabilities).

Turn all your old phones and tablets into powerful WiFi home automation controllers with the BroadLink® system!

If you want to take it even further and add support for many other system hubs like Alexa®, Wink®, SmartThings®, Vera® and Wemo®, take a look at the Home Assistant home automation system. Written in Python 3, it is an excellent system that runs on any platform (Raspberry Pi included) and supports literally hundreds of devices, including our blind motors and skylight/window openers via the BroadLink® plug-in.

battery operated wireless window openersYou'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 windows. We also have a wireless, battery operated opener (left).

It is easy to adapt these chain drive units to most types of windows and skylights because they do not need to rotate in any way like hinged units do. The flex chain simply emerges from the housing in a straight line and pushes the window or skylight open (or anything else you want to move).

It should be noted that window 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.

If you are planning to use actuators for lifting heavy skylights, you can offset the weight of the skylight with gas shocks, torsion springs, or external counterweights.

It should also be noted that the window, skylight or whatever object you want to move should be able to move freely. In the case of windows, for instance, you may have to remove the existing manual mechanism in order to allow the window to move freely.

The above installation our standard series 12 volt electric window opener for controlling vents, windows, skylights, shutters 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. The unit can exert a push/pull force of approximately 20 lbs before the obstruction sensor will stop it.

You can also extend our system with the Vera wifi link and use your phone, tablet or laptop to control all these devices (and other items) from home or while you are away.

The flex link direct push drive has an adjustable stroke of up to 300mm (12"), the opening/closing force is approximately 20 lbs (9 kg), current consumption is ~1.5 A.

Use it to control the motion of anything you want, including windows, greenhouse vents, skylights, etc.

electric window opener installation example - awning typeIt can be adapted to work with most types of windows: single hung, double hung, hinged casement, skylights, etc. The internal electronics provide motor overload cutoff and travel limit stops.

It should also be noted that the window, skylight or whatever object you want to move should be able to move freely. In the case of windows, for instance, you may have to remove the existing manual mechanism in order to allow the window to move freely.

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.

These units do use safe low voltage (12v DC), with no high voltage shock hazard present.
