Expandable window barriers are designed for applications where aesthetics are a key consideration. The expandable window barrier does not use top or bottom tracks. The square steel lattice sections are connected by high tensile rivets and allow the expandable window barrier to fold to just 15% of its locked size. In addition, a unique hinge aside facility enables each sash to turn through up to 180 degrees, thus enabling unrestricted access to be retained.

All components are phosphate treated and finished in a resilient white gloss coating. The expandable window barrier provides an attractive visual deterrent against traditional break-in methods. The wide range of standard stock sizes can be quickly and easily fitted in almost any setting.
