A sidebar article on page 80 of the March/April 2013 issue of Window & Door Magazine notes how WOCDs (window opening control devices) are gaining traction in the window hardware market. Aaron Mundt, Truth's Hinged Window Product Manager, agrees that the product line has gained popularity in the past year and mentions that Truth's SafeGard WOCD meets the ASTM F2090-10 specification. He anticipates the WOCD code requirements will become more widely enforced, resulting in the need to apply these devices at the factory, as well as retrofit in the field.

Designed to prevent children from falling out of windows, WOCDs limit how far the window can be opened during normal operation. They incorporate a release mechanism that allows the sash to be raised higher to meet emergency escape and rescue requirements. Safety features are becoming a greater concern for many homeowners and Mundt says that the awareness of, and desire for WOCDs is a good example of this increased interest.
