The Brighton Fastener is a highly popular sash fastener. Our Brighton Fastener is manufactured from brass and is a heavy duty design, ideal for larger windows.
The “Hinged arm” pivots from the vertical open position to the keep. The arm is threaded and the lock tightens by “screwing down the arm” onto the front face of the keep and sliding the keep closer to the fastener,to pinch the sashes together at this point. The hook hinges over and when tightened, pulls the keep towards the main housing pulling the meeting rails together to improve the seal at that point.
