Product Information
Full details
The Nainova Hardware UPVC Door Handle is designed for homeowners and contractors seeking a durable, high-performance replacement or upgrade for exterior doors. Its primary benefit lies in its universal, reversible design and spring-cassette mechanism that prevents handle sag, offering smooth, reliable operation on uPVC, composite, and timber doors. One important caveat is that users must verify their door's specific dimensions, particularly the 92mm PZ center and 210mm screw-to-screw distance, to ensure compatibility before purchase.

FAQs
Does this handle set include a locking cylinder?
No, this is a handle-only set. You will need to use your existing Euro-cylinder lock or purchase one separately.
Can I use this on a wooden door?
Yes, the kit is designed to be compatible with timber, composite, and uPVC doors provided the dimensions align.
What is the PZ center measurement?
The PZ center is 92mm, which is the distance from the center of the spindle hole to the center of the keyhole.
Is this handle suitable for outdoor use?
Yes, it is manufactured with high standards for corrosion resistance, making it ideal for front, garden, and patio doors.
How do I switch the handle for a left-handed door?
The handle is fully reversible; simply rotate the lever to the desired orientation before fixing the backplate to the door.
Troubleshooting
Handle remains loose or sags after installation
Check that the spring cassettes are properly seated in the backplate and ensure the screws are tightened securely.
Handle does not align with the door lock
Verify that your door has a 92mm PZ center dimension; if your lock centers differ, the handle will not engage correctly.
Lever feels stiff when operating
Ensure the spindle is not too long for the door thickness and check that the mounting screws are not overtightened, which can cause binding.

Setup, Compatibility & Care
Before installation, ensure your existing door matches the 92mm PZ (center of spindle to center of keyhole) and 210mm screw-to-screw measurements.
- Remove the old handle set and measure the existing hole spacing.
- Configure the lever direction by rotating it to the desired position for your door swing.
- Use the appropriate screw and spindle length provided in the kit based on your door thickness.
- Secure the handles and test the latch release mechanism.
For maintenance, wipe the handle periodically with a soft, damp cloth to remove grit or salt buildup, which helps maintain the corrosion-resistant finish.
