Interlock's Window Opening Control Device (WOCD) is a revolution for the residential fenestration industry. The innovative device limits the opening of casement windows but can also be disengaged to allow the window to fully open. The function and performance are compliant to the ASTM F2090 Standard Specification for Window Fall Prevention Devices. With the window partially open, simply press the red button and then press downward on the red section of cable to disengage the device. To re-engage the limit device, simply close the window. Interlock's WOCD will automatically re-engage!
The Interlock WOCD for casement windows greatly improves the user experience due to its innovative design and intelligent features.
