Product Description

Achieve a seamless, high-end aesthetic with the 10-Inch Concealed Window Hinge, the ultimate hardware solution for modern casement and awning windows. This professional-grade 10-Inch Concealed Window Hinge is engineered to be completely hidden from view when the window is closed, creating clean, uninterrupted sightlines that elevate any architectural design. Crafted from premium 304 stainless steel, the 10-Inch Concealed Window Hinge provides exceptional strength and superior corrosion resistance, making it ideal for demanding exterior applications where weather exposure is a concern. The robust 10-inch arm delivers the necessary leverage to smoothly and safely operate heavy window sashes, while the integrated 3-way adjustment system (height, depth, and compression) allows for precise calibration to ensure a perfect seal and effortless operation for years to come. The 10-Inch Concealed Window Hinge is the top choice for architects, builders, and discerning homeowners who will not compromise on aesthetics or performance.

How Does the “Concealed” Design Work and What Are the Advantages?

The “concealed” feature of the 10-Inch Concealed Window Hinge means all functional components are mortised into the window frame and sash, leaving zero visible hardware on the surface when the window is closed. This is accomplished through a two-part system: a cup housing the mechanism installed into the sash and a base plate set into the frame. The primary advantage of the 10-Inch Concealed Window Hinge is its clean, minimalist appearance that complements contemporary and high-end traditional designs. Beyond aesthetics, because the 10-Inch Concealed Window Hinge is protected within the woodwork or uPVC, it is more durable, less prone to damage from the elements, and resistant to tampering, ensuring long-term reliability.

What is the Maximum Weight Capacity for a Single Hinge?

The 10-Inch Concealed Window Hinge is built for heavy-duty performance. A single hinge can typically support between  (40-55 kg), with the long 10-inch arm providing critical leverage and stability to prevent sash sag. For a standard large casement window, two 10-Inch Concealed Window Hinges are used, effectively doubling the safe working load. It is essential to calculate the total weight of your window sash and consult the manufacturer’s specifications for the 10-Inch Concealed Window Hinge to determine the correct quantity for your project, ensuring safe, smooth, and reliable operation.

 Is This Hinge Suitable for Exterior Windows in Harsh Climates? 
Yes, the 10-Inch Concealed Window Hinge is exceptionally well-suited for exterior use, even in coastal or high-humidity environments. This is due to its construction from 304 stainless steel, which offers excellent resistance to rust, corrosion, and pitting caused by rain, salt spray, and temperature fluctuations. When paired with proper weather sealing, the 10-Inch Concealed Window Hinge will maintain its structural integrity and smooth functionality for decades, providing a durable and weatherproof pivot point for your most important windows.

How Do the 3-Way Adjustments Benefit Long-Term Performance?
The integrated 3-way adjustment system is a critical feature that sets the 10-Inch Concealed Window Hinge apart. After installation, fine-tuning with an Allen key allows for:
1. Height Adjustment: To vertically align the sash within the frame for an even gap.
2.  Depth Adjustment: To move the sash closer to or farther from the frame, ensuring consistent contact with weather-stripping and preventing air/water infiltration.
3.  Compression Adjustment:  To control the closing pressure, guaranteeing a tight seal and accounting for seasonal wood movement or settling. This adjustability in the 10-Inch Concealed Window Hinge ensures optimal performance, energy efficiency, and ease of use throughout its lifespan.

10-Inch Concealed Window Hinge – Invisible Pivot
Installing the 10-Inch Concealed Window Hinge is a precision task that requires specific tools and expertise, typically performed by experienced window fitters or carpenters. Essential tools include a 35mm Forstner drill bit or a dedicated hinge cup boring bit to create the recess in the sash, and a router with a matching jig or a sharp chisel to mortise the base plate into the frame. While the 10-Inch Concealed Window Hinge delivers an unparalleled finish and function, its installation is a professional-grade procedure due to the precise mortising required for a flawless concealed fit.
