The DUFIX DX 172 Lever on Rose – DX Series is a high-performance door handle solution designed for both residential and commercial use.

In this blog, we’ll explore how the DUFIX DX 172 works, its key benefits, applications, and how to choose the right finish for your needs.
What is the DUFIX DX 172 Lever on Rose?
The DUFIX DX 172 is a lever-on-rose door handle – a modern alternative to traditional lever-on-plate designs. Unlike rectangular backplates, this design mounts the lever on a circular rose (escutcheon), typically 50-60mm in diameter.
The DX 172 belongs to DUFIX’s DX Series, known for:
-
Smooth spring return – The lever automatically returns to horizontal after use
-
Premium PVD finish – Physical Vapor Deposition for maximum durability
-
Ergonomic lever profile – Comfortable grip for daily use
What’s the difference between DX 171 and DX 172?
While the product page would confirm this, typically:
-
DX 171 – Likely a straight lever design
-
DX 172 – Likely a curved or more ergonomic lever design
The number change usually indicates a different lever shape or rose size. Check the product page photos to compare.
Key Benefits of the DUFIX DX 172
1. Premium PVD Finish – Maximum Durability
The standout feature is the PVD (Physical Vapor Deposition) coating. Unlike standard paint or plating, PVD bonds to the metal at a molecular level, offering:

Scratch resistance – 5-10x harder than standard finishes

Tarnish-proof – Will not fade, discolor, or corrode
-
Fingerprint resistant – Easy to maintain
-
Long warranty – Typically 5-10 years

The DX 172 likely features a curved or sculpted lever that:
-
Fits natural hand position – More comfortable than straight levers

Reduces wrist strain – Ideal for high-traffic doors
-
Better grip – Especially for elderly users or children
3. Sleek Lever on Rose Design
The circular rose (escutcheon) offers several advantages:
-
Clean aesthetic – Minimalist, unobtrusive look
-
Fits any door – Works on both pre-bored and new doors
-
Easier cleaning – No crevices for dust accumulation
-
Modern appeal – Preferred for contemporary interiors
4. Smooth, Quiet Operation
DX Series levers feature:
-
Spring-assisted return – No sagging or drooping over time

Quiet latching – Nylon or rubber components reduce noise

Ball bearing pivot – Smooth rotation for years
