ABSTRACT:
A hurricane window brace arranges brace elements at upper corners of a tilt sash so that the brace elements extend from a plow region of the sash into inside corners of a shoe channel in a resin jamb supporting the sash. When so positioned, the braces maintain a distance between the inside corners of the shoe channels and the plow regions of the sash so that the upper corners of the sash cannot be moved or tilted inward by wind force. Moving the braces upward or laterally, when wind force resistance is not required, allows the sash to tilt.
