    Heavy duty window hinge

    Heavy-Duty Hinges

    Our heavy-duty hinges are designed for smooth and effortless operating of crank-to-open windows, such as Casement windows. The hinge system comes with adjustable friction screws so you can control the level of effort required to open on close each window. When opening and closing, the hinges serve to balance the window sash and the delrin shoe is equipped with stainless steel reinforcement to provide continuous, fluid action with a very solid support.

    Window Mart custom matches the size of the hinge to the height and weight of each individual window sash. The varied hinge sizes are designed to balance the weight of the windows and prevent common issues such as window chatter (vibration due to friction as a result of unbalanced windows).

    Additional available options include:

    • corrosion-resistant non-magnetic stainless steel package
    • adjustable stud
    Encore Locking System

    Encore Operator

    Encore Operators provide ease of operation and maximum strength for hinge-operated windows, such as casement or awning windows. Each Encore Operator comes with a snap-fit cover and streamlined full-flip folding handle to prevent collapse during operation. Encore operators deliver perfectly balanced performance and style.


    • High-pressure die-cast zinc operator housing, crank handle and knob
    • Hardened steel drive worm and gear
    • High-quality plastic operator cover

    Corrosion resistance

    Each Encore Operated is constructed with corrosion resistant hardware. The proprietary multi-stage coating process produces a superior finish that is as attractive as it is functional. Additionally, it is resistant to a wider range of corrosive materials, including industrial cleaning materials and environmental pollutants. Tests show that this coating process is approximately three times more effective than common zinc plated finishes when it comes to performance.


    The Encore Operator’s hardware is finished with durable coatings that have been electrostatically applied. When combined with the high-quality molded plastic cover, our awning and casement window operators provide excellent resistance to chipping, scratching, corrosion, and color fading (even with chronic exposure to UV radiation).

    Encore Operator Handle & Cover

    Both of Window Mart’s Awning and Casement window options come with high-quality and contemporary designed handles and covers. In combination with the Encore Operator system, the Encore Handle & Cover serves to make every window attractive and operational.

    Full-Flip Handle

    The design of the Full-Flip Handle helps in maintaining its “open” position without retracting in on itself during operation. The Full-Flip Handle provides smooth operation paired with a sleek and contemporary look when nested. This handle design also allows for the easy removal of window screens, as needed, without any additional steps (as is the case with other crank handle designs).

    Snap-Fit Cover

    The Snap-Fit covers can be easily removed when painting or staining a window frame. Its design provides an elegant yet contemporary look for your windows. All of Window Mart’s Encore Operator Covers come with an integrated snap feature that does not require any fasteners for cover attachment and installation. This unique characteristic of the snap-fit covers keeps your windows looking immaculate and can even hide minor installation damages.
