Why Mul-T-Lock cylinders
Restricted by patent
Mul-T-Lock quality standard cylinders are all high security and restricted by patent. They are available in various shapes and configurations, offering a range of security solutions for any project requirement.
Mechanical or electronic
Most cylinders are available as mechanical, or as CLIQ electronic access control cylinders, so a system can start mechanical and gain electronic control later.
Master key systems
Mul-T-Lock supports a range of restricted master key solutions for different requirements and business sectors. The ability to incorporate a wide range of product types into one system using a single key allows the locking system to scale with your business.
Access to authorised areas only
Keys are mastered to provide each user with access to authorised areas only, increasing access control while reducing the number of keys in circulation. The mechanical hardware can be enhanced with electronic locking for an additional layer of security.
CLIQ cylinders
Mul-T-Lock CLIQ cylinders offer complete access control and master key capability in every cylinder. Each CLIQ cylinder is an electromechanical hybrid that combines electronics and mechanical function in one.
A patented floating element
Mul-T-Lock cylinders and keys include a special patented floating element that meets the highest security standards, with the most sophisticated security features available.
One key across the system
Single key access is more efficient, reducing initial costs as well as future budgets spent on replacement keys. Camlocks and cupboard locks take the same key, and modular cylinders let you create the right size on the spot in sizes from 31mm up to 80mm per side.
