Thumbturn cylinder fitting
Will a thumbturn fit every existing lock?
The cylinder format, cam and surrounding fittings must be compatible with the mechanism.

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