This Quadrant Arm Stay in Polished Brass is part of our Dart range of Window Hardware, offering a traditional and practical addition to a bottom-hung casement window. This product has been designed to allow the window to open to approximately 30 – 40°, preventing the casement sash from falling. The shape of the arm allows the window opener to sit on the end for ventilation. When fitted the quadrant stays will only allow the window to open to a fixed safe distance. Usually, they are fitted in pairs to support the casement as it falls inwards.Not only does this product provide a practical solution to allowing ventilation in your home, the 4 finishes available offer a stylish and decorative touch adding sophistication and elegance to your windows.Fixed position that projects into the roomThe receiver plate protects the sashIncreased strength and durabilitySuitable for bottom hung casement windowsSupplied in pairsComplete with ScrewsMaterial: Cast BrassSize of Stay: 200mmChoose from four finishes: Antique Brass, Polished Brass, Polished Chrome or Satin ChromeAvailable in two sizes: 152mm or 200mmPerfectly matched with the Dart Fanlight CatchPart of our Dart range of Window HardwarePlease note: When fitting YOU MUST pre drill the screw holes or use a similar sized pozi screw to make the thread of the screw in the window first.
