MT5 Mul T Lock Euro K&T Cylinders (R Denotes Side Of Turn)

The Mul-T-Lock MT5 Euro Key & Turn (Thumbturn) Cylinder offers premium, high-security protection for domestic and commercial doors. Combining advanced mechanical engineering with patented key control, the MT5 platform is designed to resist common forms of cylinder attack, including picking, drilling, and bumping.

This cylinder features a double locking mechanism, integrating Mul-T-Lock’s high-precision telescopic pin tumbler system alongside the patented Alpha Spring. The Alpha Spring is a unique mobile element at the tip of the key that engages a special pin at the rear of the cylinder to create an additional shear line, providing superior manipulation resistance.

For enhanced security, the MT5 system uses restricted key control. Keys are supplied with a unique coded magnetic authorization card, ensuring that additional keys can only be duplicated by authorized dealers upon presentation of the card.

Important Ordering Information: When choosing an offset cylinder, please ensure you select the correct side for the thumbturn. In the options below, the letter 'T' (or 'R' in manufacturer codes) denotes the side of the cylinder where the thumbturn is located (e.g., T35x45 indicates the thumbturn is on the 35mm side, and the key is on the 45mm side).

These cylinders are available in a wide range of sizes and in both Nickel and Brass finishes. Please select your required size, finish, and turn configuration from the options below.
