How does a window opening control device work?

A window opening control device limits a window to opening less than 4 inches to provide additional window fall protection for children or others. It’s designed to disengage, so the window can be fully opened in an emergency.

When is a window opening control device needed?

This feature might be one that a customer opts to add for the safety of their children or others. It can also be used to meet requirements for window fall protection as outlined in the International Building Code. When an operable window is more than 72 inches above finished grade or other exterior surface below and has a sill height of less than 24 inches (as measured vertically from the floor), this device can bring windows into code compliance.

How to order a window opening control device?

Window opening control devices can be built into a new window or applied as an accessory:

1) A window opening control device can be built into certain new windows. Factory-applied, flush-mount hardware creates a sleek look that doesn’t interfere with aesthetics or installation (no extra steps required). Find this option available with 200 Series Double-Hung Windows and 400 series Double-Hung Windows.

2) A window opening control device kit can be ordered as a solution for an existing window or a new window that doesn't come with the option to add factory-applied hardware. The easy-to-install accessory is available with casement, gliding, single-hung, or double-hung windows in our Parts Store.

No matter which option is right for your project, you can count on the window opening control device to help you meet both customer needs and code!
