Parallex

Preferred Engineering Products offers a revolutionary hardware system designed to make window operation a breeze.

The patented Parallex system offers unmatched ease of use with a single handle operation for slide, tilt and multi-lock function on hung and slider windows. Our unique casement and awning hardware completely eliminates the use of a crank. Parallex is effortless and safe to operate while delivering improved ventilation, maximized egress, and increased security from hidden locks.It’s no wonder homeowners ask for Parallex by name.

With Parallex hardware, window sashes swing inward to offer increased ventilation, while making cleaning exterior glass a snap. The optional SLIDE‘N'HIDE integrated roll-away insect screen provides increased visibility.

Parallex is available for use in any of the following window applications:
