Window Safety Features and Options
Enhanced window safety for what matters most
Window safety is essential for protecting your loved ones, and Infinity from Marvin offers two distinct solutions to meet your specific needs and style preferences — Sash Limiters and Window Opening Control Devices (WOCDs).
Why choose Window Opening Control Devices
Our WOCDs limit window opening to 4 inches or less, helping prevent accidental falls while maintaining full functionality with a simple two-action release. These child safety window guards provide essential protection for your loved ones.
Safety with style
Designed to provide peace of mind without compromising the elegant look of your Infinity windows, our window safety locks offer protection for the whole family.
Seamless integration
Thoughtfully integrated into your window design with factory-applied precision, these safety window stops work with your existing windows.
Effortless operation
Simple two-step release for full window function when needed, with automatic reset of safety latches that re-engage when windows are closed, ensuring consistent protection without manual reactivation.
Code compliance
Meets ASTM F2090-17 window standards required by building codes while maintaining egress capabilities.
A perfect match for your style
Enhance your home's safety with our window safety products, 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 enhanced safety and a beautiful, cohesive look.
Available for double hung, casement, slider, and awning windows, our window safety locks come in finishes that perfectly complement your window selection.

Infinity Double Hung
The double hung window opening control device sits on both sides of the top sash. When you open the window, it automatically stops at 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 window sash limiter resets on its own.
Available finishes: White, Beige, and Black

Infinity Slider
This practical sliding window opening control device limits your slider window to a 4-inch opening. When you need more air or access, 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 safety window stops automatically reset.
Available finishes: White, Sierra, Satin Taupe, Oil Rubbed Bronze, and Matte Black

Infinity Casement
A simple but effective casement window safety locks system that uses a tether cable with a catch that limits opening to 4 inches. When you want to open the window completely, just push the red button and slide the lever. Close the window later, and the casement window safety limiter kicks right back in.
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.

Sash limiters
Sash limiters are basic window safety features that restrict the opening distance for Infinity Awning and Casement windows to 4 inches. These window safety bars are a way to meet your local building codes while providing child-safe sash windows.
All Infinity sash limiters and window safety locks are covered under our Limited Lifetime Warranty.
