The 1591FF Mild Steel Stormproof Hinges with unequal leaf configuration are specially designed for use in stormproof and weather-resistant window installations. Constructed from high-quality mild steel, these hinges provide exceptional strength, stability, and rust resistance, making them ideal for external wooden or metal-framed casement windows.

The unequal leaf design allows one flap to sit flush within a rebate, offering enhanced weather sealing and smooth opening/closing action. This makes the 1591FF a reliable choice for outward-opening sashes where airtight and watertight performance is critical.

Finished with a protective coating for enhanced durability, these hinges are perfect for use in residential, commercial, and industrial applications, particularly in areas exposed to wind, rain, or fluctuating temperatures.
