Interlock's WOCD II

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.

• The flexibility of the Sash Connector and built-in sash lifter ensure automatic reengagement every time and no need for future adjustments.
• Faster, easier disengagement is possible because the Sash Connector can be released before the window reaches the maximum allowable opening.
• Cleaning and maintenance of an open window can be performed without additional care because the flexible, stainless steel Sash Connector will not bend due to accidental contact when disengaged.
• The compact design fits a variety of casement and awning windows and accommodates vertical or horizontal placement.
• Restriction distance can be adjusted before or after installation to ensure any window thickness is limited to the maximum allowable opening.
• Installation is simple thanks to self-locating features providing a proper fit every time.
• Tested load capacity and cycle durability meet the requirements of ASTM F2090-21.
