Security chain fitting
Does a chain replace the main door lock?
It provides a limited-opening function and is not a substitute for the entrance's main securing system.

Security chain fitting — planning the work
For security chain fitting, dimensions alone do not define a suitable pane. Glass construction, edge support and the surrounding frame affect the specification and fitting arrangements.
