Thumbturn cylinder fitting
A thumbturn changes inside operation, so its suitability should be considered alongside the door's locking system.
Thumbturn cylinder fitting — verify internal thumbturn clearance while operation, with the installation method, protection and finishing details planned.
Confirm the cylinder profile and measurements as well as the building's operating requirements. Shared entrances and specified doors may need additional approval before hardware changes.
