## Overview

The Andersen Double-Hung Window Opening Control Device enhances safety by limiting window openings to less than four inches, while allowing for full ventilation and emergency escape when needed. This kit includes both right and left-hand devices, is easy to install with a bonus precision mechanical pencil, and features an automatic reset function for continuous safety.

## Description

The Andersen double-hung window opening control device kit includes a right and left-hand device. The devices are installed on both sides of the sash and limit the opening of the venting sash to less than four inches when the sash is first opened. Release of the device allows the sash to be further opened for full sash ventilation and/or emergency escape and rescue. The opening control devices are automatically reset once the sash is returned to its fully closed position. The double-hung opening control devices meet requirements of ASTM F2090-08 and ASTM F2090-10 for Window Fall Prevention Devices With Emergency Escape and (Egress) Release Mechanisms. 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 if this device is accepted as an alternative to the minimum sill height requirement. Children are naturally curious and often want to explore what is on the other side of a window. As part of a window safety program: Look Out For Kids program in 1992 to teach both kids and adults the basics of window and patio door safety. Will Only Work With Andersen Brand Windows including: A-Series Double-Hung Windows, 200 Series Narroline Double-Hung, 400 Series Woodwright Double-Hung, 200 Series Tilt-Wash Double-Hung & 400 Series Tilt-Wash Double-Hung.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great babyproofing for our Andersen windows
*by A***S on June 29, 2018*

Great babyproofing for our Andersen windows. They look great and I'm glad they're available on Amazon for less than the full retail price. They are pretty easy to install (just need a drill and screwdriver), even though it's a little scary to drill into your windows. The kit even comes with a mechanical pencil to mark your window, so I have a bunch of extra pencils now. As far as how effective they are, the kids have now taken to climbing on the windows and toggling these, but at least there's 2 on each window, so there's an extra layer of security.

### ⭐⭐⭐⭐ Works well for what it is
*by A***R on March 2, 2021*

Used on non-Anderson windows so I had to make small spacer blocks and use longer screws. Worked fine but I think if someone was determined enough to get in they could probably force these open. Still they are better than alternatives that I have seen.

### ⭐⭐⭐⭐⭐ Effective child locks
*by C***R on November 22, 2019*

Very effective for certain Anderson windows as a child safety lock. It allows for easy complete opening while stopping them at a 3-4 inch height for children. Be sure to check that you have the correct windows. Reasonable installation. Allow at least 30- 40 minutes for the two locks. Once you understand how it works, you can do others much quicker.
