Lincoln Windows & Patio Doors


Double Hung Window Sash Limiter

Every year thousands of children in the United States are injured from falling out windows. Lincoln encourages all consumers in the market for double hung windows to install fall prevention devices to help reduce accidental falls. Lincoln’s new optional sash limiters meet the requirements of ASTM F2090 and are available in two finishes, including white and chrome. Lincoln also offers sash limiters for their line of casement windows.

ASTM F2090 (2008): Standard Specification for Window Fall Prevention Devices With Emergency (Egress) Release Mechanisms establishes requirements for devices intended to address the risk of injury and death associated with accidental falls from windows by children five years old and younger.

ASTM-compliant window opening control devices, such as those offered by Lincoln:

  • Allow a window to be opened less than 4 inches.
  • Allow a window to be fully opened if needed as a means of escape or rescue in an emergency.
  • Resets automatically every time the window is opened.

Window Safety Tips

  • Windows often serve as a means of escape during an emergency, such as a fire.  Be prepared by having an emergency escape plan.  Practice it regularly as a family and teach children how to safely exit through windows.  Make sure each window opens easily and is free from clutter.
  • When children are around, keep windows closed and locked.  If ventilation is needed, open windows they cannot reach.
  • Unattended children run the greatest risk of falls, so they should always be supervised by an adult while playing.  Teach children not to play near windows and keep furniture and other items they can use as a climbing aid away from windows.
  • Do not depend on screens to prevent falls.  Instead, install fall prevention devices that meet American Society for Testing and Materials (ASTM) requirements, featuring quick release mechanisms that allow for easy escape during an emergency.
