High-security 3-star cylinder - MTL™300 Break Secure® 3XP Pro
The MTL™300 Break Secure® 3XP Pro is a 3-star cylinder designed with reinforced protection inside and out to stop today’s most common and aggressive forms of attack. Its patented sacrificial elements work in harmony with advanced locking technology to keep the door secure even if an intruder tries to snap the cylinder.
A concealed cam provides anti-snap protection, keeping the lock engaged after a snap attempt. A specially designed locking mechanism adds another layer of security, designed to break in a controlled way to protect the cylinder’s core. Combined with precision machining and a hardened body, the result is a cylinder that doesn’t just resist attacks – it’s built to outthink them.
