The British Standard Keyless Egress Nightlatch Door Lock is a high security door lock with a classic and robust design. This lock conforms to British Standard 8621:2007 which mirrors the BS 3621:2017 but for 'escape locks' and meets the tough criteria/requirements laid down by insurance companies and the police. Locks meeting these requirements are classified as providing keyless egress at all times. This applies where there is a requirement for an easy action method of opening an external door from the inside with no need for keys or similar devices for unlocking. Especially relevant for entrance doors in multi-residential and other buildings. A keyless lever on the inside of the door ensures it is possible to make an emergency escape in an event of fire.
