LocksOnline Imperial 5-Lever Mortice Locks

Now considered the base form of security for main door applications, five-lever locks are the most common form of lever locks used on front doors and other entrance doors, due to their improved security over that of a 2 or 3 lever configuration.  

Manufactured in the UK, these Imperial Locks are still designed and produced right out of the Guardian Lock & Engineering Co factory in Willenhall, England.   Their 3-lever lock range includes both sashlocks and deadlocks, mostly used now for internal doors as the security is much lower than that of a 5-lever lock or similar. 

Amongst these five-lever locks, we also have British Standard (BS3621) locks, which go one step futher on their security, having been tested under British Standards to conform to the latest security standards.  If high security is required, we always recommend BS3621.   This may also be requested in some insurance policies.
