This patent describes an extremely simple and inexpensive means to limit the tilt of hung window sashes. Complete devices can be stamped from a single 1/2" wide strip of spring stainless steel or used with stamped or injection molded components for fastener-less snap-in assembly and child resistant operation.

THE CHOICE IS YOURS. This patent protects broad variations on manufacturing, installation and use options. All Tilt Limiters™ are invisible when the sashes are closed and engage automatically as they are tilted open.

Products covered under this patent can be designed for non-handed installation or one-size-fits-all components.They can also use existing assembly screws for installation, or be added to existing products with no or minimal assembly line tooling. Minimal inventory and fast installation are an important Tilt Limiter™ feature that will quickly become an industry standard for all aluminum and vinyl hung windows.
