Heavy-duty mechanical locks with on-door code change function.
Simple and quick control of coded access.
Traditionally code changing on mechanical locks has required the lock to be removed from the door; the CL600 is the first mechanical lock from Tell where on door code changes can be made in seconds! The CL600 Quick Code system brings significant advantages to commercial users such as hospitals, schools and local authorities. The locks allow for various ways of managing entry by code or by key.
