Sash Locks

If properly maintained, locked, and monitored, sash window locks are a good form of security. The most secure locks are the Fitch locking devices since they have a half-circle catch that’s hard to open.

With a sash lock, you can open and close the window without worrying about it locking automatically and you only need the key only every now and then. Available in various security levels to suit your requirements, Mortice Sash Lock’s are also approved by insurance companies.
