Window Opening Control Device

Andersen window opening control devices are designed to meet ASTM standards for window fall prevention devices with emergency escape and rescue release mechanisms. These devices are intended to prevent accidental falls by children aged five years and under through open windows while allowing for the intentional opening of a window as may be needed for escape, rescue or ventilation. Proper location and installation of these devices to allow a less than 4 inch opening is required to meet the ASTM standard. Each device comes with a hang tag that indicates the device was tested to the ASTM standard. This tag should remain on the device until final code inspection, if required.

Andersen now has window opening control devices available for the following products:

Window Opening Control Device for Casement Windows 

Window Opening Control Devices for Casement Windows

The window opening control device offering for Andersen casement windows is:

  • A simple, orange push-button release that clearly identifies the release mechanism of the device, and an innovative flip cap shields it from accidental release. Opening the flip cap and pushing the release button are the two steps required to release the sash.
  • Releasable with the insect screen in place and automatically reengages when the window is closed.  Therefore, the screen can stay in place and the sash can be released for ventilation without letting in insects.
  • Made of corrosion-resistant* stainless steel, the device is neatly displayed on the sill stop of the casement window.
  • Available for A-Series and 400 Series casement windows and 400 Series casement windows with Stormwatch protection in standard and custom sizes.
  • Able to be installed on existing Andersen A-Series and 400 Series products manufactured since 1995. A reusable hardware installation kit is available when ordering.

**Andersen window opening control devices meet the requirements of ASTM F2090-08 (2008 edition) and -10 (2010 edition), entitled “Standard Specification for Window Fall Prevention Devices with Emergency Escape (Egress) Release Mechanisms.” These ASTM standards require a window opening control device to:

  • Limit the sash to open to a less than 4-inch dimension.
  • Be deactivated via one dual-action or two independent actions. Such actions then allow the sash to be fully opened as may be needed for emergency escape, rescue or ventilation.
  • Re-engage when the sash is closed so that the next time the sash is opened, it again stops at a less than 4-inch dimension.

Window opening control devices may provide a potential alternative (compared to a window guard) to meet minimum sill height code requirements contained in the 2006, 2009 and 2012 editions of the International Residential Code (IRC) and International Building Code (IBC).  Always check with your local code official for all local code requirements and to determine if the minimum window sill height code has been adopted in your area and to determine whether device is acceptable as an alternative to the minimum sill height.
