The Betley Butterfly Stormproof Cranked Hinge is designed for contractors and DIY enthusiasts who require durable, weather-resistant hardware for top-hung vent lights, side-hung timber casement windows, and rebated doors. These 63mm hinges provide smooth, controlled movement, making them an excellent choice for caravans and properties in coastal environments where corrosion resistance is essential. While the yellow passivated finish offers superior longevity, users should note that the hinge dimensions are specific and must be verified against existing door or window rebates before installation.

Yes, the yellow passivated finish is specifically designed to provide enhanced resistance against salt air and moisture, making it suitable for coastal locations.
These hinges are primarily designed for timber casement windows. They may not be compatible with the specialized profiles required for uPVC frames.
The hinges feature a 2.5mm leaf thickness, providing high strength for standard window and door applications.
This set includes 10 pairs of hinges, totaling 20 individual hinge pieces.
The cranked shape allows the hinge to accommodate the offset between the window sash and the frame, ensuring a tight, stormproof seal.
You will need a drill for pilot holes, a screwdriver, and a chisel to ensure the hinges sit flush within the timber rebate.
Check that the hinges are properly recessed and that the screws are fully tightened; adjust the rebate depth if necessary.
Apply a small amount of silicone-based lubricant or light machine oil to the knuckle mechanism.
Gently clean the affected area with a soft cloth and re-apply a protective metal sealant if the passivated layer has been breached.
Installation requires basic woodworking tools, including a chisel for rebating the hinge into the timber and a drill for pilot holes to prevent wood splitting. Ensure you align the knuckle correctly with the window axis to guarantee smooth operation.
Compatibility: These hinges are compatible with most standard timber casements and rebated doors. Always verify your existing hinge length (63mm) and knuckle diameter (9.0mm) before purchasing.
Care: While the passivated finish is designed for durability, you should inspect the hinges annually for any signs of surface wear. If the hinges become stiff, apply a light, non-corrosive machine oil to the knuckle to maintain smooth movement. Avoid using abrasive cleaners on the finish, as this can strip the passivation and expose the metal to rust.
