Bathroom Thumbturn Set Matt Satin Black Nickel 50mm Round Rose
Typical Applications
This thumbturn set is specifically designed for internal bathroom doors where privacy is required but emergency access must remain possible. It pairs with Deanta 3 lever bathroom locks and is suitable for domestic and light commercial bathroom installations. The matt satin black nickel finish complements contemporary and transitional interior schemes.
- Domestic bathroom doors requiring privacy locks
- Ensuite bathrooms in residential properties
- Commercial properties with bathroom facilities
- Door thickness typically 35-45mm
Installation and Setup
The thumbturn set comprises a round 50mm rose with 10mm projection and a thumbturn lever measuring 25x22x8mm. The overall projection from the door face is 32mm. Installation requires a compatible Deanta 3 lever bathroom lock mechanism. The set includes a 5mm spindle which connects the thumbturn to the internal lock mechanism. Ensure the spindle is correctly inserted into the lock's spindle socket before securing the rose to the door with the provided fixings. Check that the thumbturn operates smoothly through its full range of motion before finishing.
- Verify compatibility with your Deanta 3 lever lock before purchase
- Insert 5mm spindle fully into lock mechanism
- Secure rose flush to door surface
- Test operation multiple times to confirm smooth engagement
Maintenance and Care
The matt satin black nickel finish requires minimal maintenance. Wipe the rose and thumbturn lever periodically with a soft, dry cloth to remove dust and fingerprints. Avoid abrasive cleaners or scouring pads which may damage the satin finish. If the thumbturn becomes stiff or difficult to operate, check that the spindle connection is secure and that the lock mechanism itself is not obstructed. Lubricate the lock mechanism sparingly with a light machine oil if needed, but keep lubricant away from the visible thumbturn components.
- Clean with soft cloth only
- Avoid harsh chemicals or abrasive materials
- Check spindle connection if operation becomes stiff
- Apply light machine oil to lock mechanism only if required
Limitations and On-Site Tips
This thumbturn set is designed exclusively for use with Deanta 3 lever bathroom locks and will not function with other lock types. The 32mm overall projection means it extends noticeably from the door surface, so ensure adequate clearance from walls or adjacent fittings. The satin black nickel finish, whilst durable, may show fingerprints more readily than polished alternatives. Always verify door thickness and lock compatibility before ordering. Keep the external key or coin accessible for emergency access situations.
- Compatible with Deanta 3 lever locks only
- Check 32mm projection clearance before installation
- Maintain access to external emergency key
- Confirm door thickness suits your lock installation
