Euro Profile Cylinders

The Euro profile cylinder is the standard lock core for the majority of modern residential and commercial door locks in the UK - used in multipoint locking systems on composite and uPVC front doors, and in many mortice sashlocks and deadlocks on timber doors. At the DIY Hardware Store, our Euro profile cylinders cover the sizes and security grades most commonly specified in UK residential security applications.

Euro cylinders are available in single (key one side, turn-snib the other), double (key both sides), and thumbturn (key outside, thumbturn inside) configurations. The critical dimension is the total cylinder length and the split, which must match the door thickness and lock body. Anti-snap cylinders are strongly recommended for all front door applications in the UK, as standard cylinders can be snapped with simple leverage to gain entry in seconds. Our security-rated Euro cylinders feature anti-snap, anti-drill, and anti-pick protection to provide genuine resistance to forced entry.
