MT5 Mul T Lock Threaded Mortice Cylinders

The Mul-T-Lock MT5 Threaded Mortice Cylinders (also known as screw-in cylinders) offer premium high-security protection for commercial and residential applications. These cylinders are commonly used on metal doors and are ideal replacements for lock cases from major brands, such as Adams Rite or Mul-T-Lock mortice lock cases.

Built on Mul-T-Lock's patented MT5 mechanical platform, these cylinders feature a highly advanced locking mechanism. This combines telescopic pins with a unique patented Alpha spring at the tip of the key, providing exceptional resistance against picking, drilling, bumping, and unauthorised key duplication. Each cylinder is supplied with a magnetic key card, ensuring that extra keys can only be cut by authorised dealers.

These cylinders are available in a durable Satin Steel finish with a standard 1 1/8" thread. They can be ordered as a Single cylinder, a Pair, or with a Thumb Turn configuration. Please select your required option from the list below.
