uPVC doors and other doors with multi-point locking systems. We now supply and fit the new Cisa Astral high security barrels with 10 pins as opposed to the normal 5 - 6.

They also have 2 visible steel bands running the length of the barrel to avoid 'snapping' the barrel to gain entry. These barrels also have a special clutch mechanism that allows you to open the lock with a key from the outside even if there is a key on the inside! These barrels come with 3 keys = spares can only be cut on production of a security card which comes with each lock.
