Ingersoll High Security Night Latch Locks
Ingersoll Locks Limited has been at the forefront of lock design since the company was founded in 1949. The business first manufactured a high security impregnable padlock range. Then the factory went on to produce submarine spitfire parts in WW2. Post-war 1950’s saw the D20 10 Lever Night latch, not only exhibiting in the 1951 Festival of Britain, but providing locks for the entire venue.
The 10 Lever night latch cylinder has double the levers of many other locks, this system gives a high resistance to lock picking devices, drills or skeleton keys that may be used to gain access. In 1967 a version called the ‘anti wedge’ was patented to fit over the top of the lock. And a version with a higher shoulder was introduced in 1968.
So when you choose an Ingersoll Lock you are buying into their history, quality and unique design features. One of the most popular locks was first introduced by the company over 40 years ago, the Ingersoll Classic automatic SC71 Night latch deadlock is a very high security lock. A firm favourite since its launch in 1969, it is available in brass and chrome finishes and has sold over 2 million in the UK, not to mention the rest of the world.
The next big milestone in the company’s history came in the shape of the 1979 launch of the NS80, this Night latch lock received the company’s first ever British Standard Certification (BS 3621) for its theft resistance.
Ingersoll locks have such a high reputation in the US that the government has decided to use them as standard as on all high security jobs. Ingersoll pride themselves in being used for the toughest and most difficult jobs and pride themselves in protecting their customers from intelligent and persistent thieves.
