Full details
The Carlisle Brass M34 Oval Mortice Door Knobs are designed for homeowners and contractors seeking a robust, high-visibility door handle that balances comfort with heavy-duty performance. Featuring an ergonomic, larger-than-average oval shape, these knobs provide a secure grip, making them an excellent choice for demanding residential or commercial environments where durability is paramount; however, users should note that the half-sprung design requires specific attention during installation to ensure proper alignment and tension for both knobs.

Are these knobs compatible with all door thicknesses?

Can I use these on exterior doors?
These are primarily designed for internal use. Check if your specific door environment is protected from harsh weather.
What is the warranty period?
This product is covered by a 10-year mechanical guarantee.
Does the package include two knobs?

What are the dimensions of the rose?

Troubleshooting
The knob does not return to the horizontal position after being turned.
Verify that the sprung knob is installed correctly and check that the mortice latch spring is not obstructed.
The door knob feels loose or wobbly.
Tighten the grub screws located on the side of the knob neck using an appropriate hex key.

Setup, Compatibility & Care
Installation requires standard mortice hardware. Since the set is half-sprung, identify the sprung knob and ensure it is mounted on the side of the door that requires the most assistance in returning the latch. Use a soft, lint-free cloth to maintain the gold finish; avoid abrasive cleaners or acidic polishes that can strip the protective coating. Regularly check the spindle and grub screws every six months to ensure they remain tight, as vibration from closing the door can loosen fixings over time.
