Oval-Compatible Hardware
What You Need with an Oval Half Cylinder
To create a complete and functional locking setup, pair your Oval Half Cylinder with the right supporting components.
Start with the Oval Profile Lock Cases – these are engineered to suit the curved profile of oval cylinders and ensure proper fitment within the door.
Match with Oval Profile Door Handles – ideal for maintaining consistent design and function across internal commercial doors and legacy setups.
Don’t forget the Oval Escutcheons – these cover the lock cylinder neatly and help protect against tampering or cosmetic wear. For easier operation, especially on heavier doors, consider adding Cylinder Pulls – they combine security with smooth access.
These accessories are essential for facilities management teams, commercial refurbishments, and projects where legacy oval-profile hardware must be maintained. Choosing compatible parts helps reduce installation issues and preserves door aesthetics while maintaining compliance.
Cylinder Sizing & Modern Advice
How to Measure & When to Choose Euro Profile Instead
Measuring an Oval Half Cylinder is simple. Unscrew it from the door and measure from the central cam screw hole to the edge. A 35/35 cylinder has equal halves, while a 40/30 would be offset.
📏 Popular sizes:
30/30, 35/35, 40/40, 40/30, 45/45
⚠️ Important: Oval profile cylinders are being phased out in favour of more common Euro profiles. If you're replacing a lock on a new door, consider upgrading to Cylinder & Turn models – especially for compliance in HMOs, commercial properties, and areas requiring internal thumbturns for fire safety. Always check if your existing lock case is compatible with oval or euro cylinders before ordering.
