Lockwood Symphony Round Rose Privacy Adaptor - 3890
The Lockwood 3690 Symphony Round Rose Privacy Adaptor is a round rose privacy adaptor designed for use with compatible Lockwood mortice lock applications where a turn snib privacy function is required. It is commonly specified with Lockwood Symphony style door furniture to provide a consistent square rose presentation across the door set.
This adaptor uses a concealed fixing design for a cleaner finished appearance and suits standard hinged door applications in residential and light commercial settings. It is intended for doors where privacy is needed rather than keyed entry control.
For Australian projects, this type of adaptor is commonly selected for bathrooms, bedrooms, ensuites, and private internal rooms where a matching architectural rose format is preferred.

Frequently Asked Questions
Is this product suitable for fire doors?
It is listed with a fire rating up to 4 hours when used as part of a compliant door system.
Does this include all required mounting hardware?
The supplied data confirms the privacy adaptor itself, but does not publish a full box contents list. Confirm lock body and any related furniture separately.
What is a common installation mistake to avoid?
Assuming it suits every mortice lock or latch can cause fitment issues. Confirm compatibility with the intended Lockwood lock function before installation.
Additional Information
- This adaptor is typically selected where a project needs round rose privacy hardware to match other Lockwood Symphony furniture on site.
- It is commonly specified in Australian residential and apartment work for bathrooms, ensuites, and bedrooms.
- A common misapplication is treating the adaptor as a complete privacy lockset. It still depends on the correct compatible lock or latch arrangement.
