Window Fall Prevention Solutions
Enhanced window features and options
Window safety is essential for protecting your loved ones, and Infinity by Marvin offers two distinct window fall prevention device solutions to meet your specific needs and style preferences — Window Opening Control Devices (WOCDs) and Sash Limiters.
Why choose Window Opening Control Devices
Our WOCDs limit the window openings to less than 4 inches and include an operable release mechanism which allows the sash to be opened for emergency egress. The WOCD will automatically reset when the window is fully closed again. These devices may prevent potential falls for children five years old and younger.
Protection
with style
Designed to provide peace of mind without compromising the elegant look of your Infinity windows, our WOCDs offer protection for the whole family.
Seamless
integration
Thoughtfully integrated WOCDs blend into your window design with factory-applied precision without detracting from the beauty and functionality of the window.
Effortless
operation
The WOCD release mechanism can be operated to allow for emergency escape when needed, and will automatically reset when windows are fully closed, ensuring consistent protection without manual reactivation.
Code
compliance
Our WOCDs meet ASTM F2090-25 requirements for use on emergency escape and egress window openings. Verify specific compliance requirements with local building and fire codes.
A perfect match for your style
Enhance your home's safety with our window fall prevention devices, while also maintaining the beauty and functionality of your windows with precision-engineered WOCDs. Designed to complement our line of windows, Infinity WOCDs complete your replacement window project with fall prevention features and a beautiful, cohesive look.
Available for double hung, casement, and slider windows, our WOCDs come in finishes that perfectly complement your window selection.

Infinity Double Hung
The double hung WOCDs sit on both sides of the top sash. When you open the window, it automatically stops at less than 4 inches. Need to open it wider? Just press the orange-marked levers and you can fully open your window. Close it, and the double hung WOCDs reset on their own.
Available finishes: White, Beige, and Black

Infinity Slider
This WOCD stops your slider window to a less than 4-inch opening. When you need emergency escape and rescue (egress), just press the red lever to reveal the black lever underneath, then slide it down. Your window can now open fully, and when you close it, the WOCD will automatically reset.
Available finishes: White, Sierra, Satin Taupe, Oil Rubbed Bronze, and Matte Black

Infinity Casement
A casement WOCD system uses a tether cable with a catch that limits opening to less than 4 inches. When you want to open the window completely for egress, push the red button and slide the lever. When you fully close the window, the casement WOCD will automatically reset.
Available finishes: White, Sierra, Satin Taupe, Oil Rubbed Bronze, and Matte Black
Note: Because of the metals used in the casement window opening control device, this product is not recommended on windows installed within one mile of salt water.
