Mul T Lock BREAK-SECURE 3XP PRO 3-STAR Euro Thumb Turn Cylinders

The Mul-T-Lock Break-Secure 3XP Pro 3-Star Euro Thumb Turn Cylinder offers top-tier security and ultimate convenience for your home. Engineered to defend against the most common forced entry methods, this high-security cylinder is TS007 3-Star accredited, Sold Secure SS312 Diamond certified, and Secured by Design approved.

At the heart of its design is an advanced anti-snap sacrificial section. In the event of an attempted break-in, the front of the cylinder snaps off cleanly, leaving the internal mechanism intact and the door securely locked. It also features robust grip-resistant technology to prevent wrenching, alongside integrated anti-drill, anti-bump, and anti-pick protections.

With a thumb turn on the inside, this cylinder allows for quick and easy locking and keyless egress in an emergency. It uses a patented keyway to prevent unauthorised key duplication, meaning extra keys can only be cut upon presentation of the included security card.

This cylinder is available in a wide variety of overall sizes to suit different door thicknesses. Please measure your door carefully and select your required size from the options below.
