The 5 lever lock is a type of lock often required for home insurance and often recommended by the police for home security. There are various grades but the current British Standard (BS3621:2007) is usually required for insurance purposes. The lever mechanism is really only seen in the UK and some parts of Scandinavia, and locks using this form of mechanism are frequently referred to as Chubb locks although there are a great many manufacturers. BS3621:2007 requires a bolt throw of 20 mm rather than the 14 mm of the earlier British Standard. Most BS3621 locks have anti pick devices built in to reduce the chance of lock picking.

Famous quotes containing the words lever and/or lock:
“Now William pulled the lever down,
And click-clack went the printing-press.
William was the only printer in town
Who had peeped while the angels undress.”
—Allen Tate (1899–1979)
“Time, which shows so vacant, indivisible, and divine in its coming, is slit and peddled into trifles and tatters. A door is to be painted, a lock to be repaired. I want wood, or oil, or meal, or salt; the house smokes, or I have a headache; then the tax; and an affair to be transacted with a man without heart or brains; and the stinging recollection of an injurious or very awkward word,—these eat up the hours.”
—Ralph Waldo Emerson (1803–1882)
