From Yale, the BS2 British Standard Nightlatch is a maximum security Nightlatch designed for timber external doors. British Standard approved and Kitemarked to BS 3621:2007, it is recommended by insurance companies and created to support a more secure everyday entrance. Key operated from the outside, it offers key and lever handle operation from the inside, with a lockable internal handle for added control. The latch automatically deadlocks when the door is closed, while the snib function allows the latch to be held back when required. A 6 pin high performance cylinder and a 20mm anti-carding bolt complete the specification, and the lock is backed by a 10 year guarantee. With a 40mm backset, it is suited to doors where space is restricted, such as glass panelled designs.
