Setup, Compatibility & Care
For a successful installation, ensure your window frame provides a flat surface for the 57mm x 19mm fixing plate. Before drilling, measure the gap between your window sash and frame to determine whether the mortice or hook plate is required. Use the provided wood screws, ensuring they are tightened evenly to prevent movement. For care, wipe the fastener periodically with a soft, dry cloth to remove dust. Avoid using abrasive cleaners or harsh chemicals, as these may damage the black finish over time. If the finish eventually shows signs of wear, a light application of protective wax or specialized metal restorer can help maintain its appearance.
