Classic

Mul-T-Lock's Classic High Security mechanical platform is designed with protective features making it resistant to intrusion attempts. Each Classic cylinder contains a special telescopic pin locking mechanism with internal and external pins.
When enhanced High Security is necessary with features such as patented key control, we recommend choosing the MTL™400, MTL™600 or MTL™800 platforms for your security needs.
