When it comes to upgrading your interior doors, choosing the right Lever on Rose is essential. The DUFIX DX 175 Lever on Rose – DX Series is a high-performance door handle solution designed for both residential and commercial use. Known for its durable PVD finish and contemporary lever profile, this handle offers a reliable way to enhance security and style.

In this blog, we’ll explore how the DUFIX DX 175 works, its key benefits, applications, and how to choose the right finish for your needs.

What is the DUFIX DX 175 Lever on Rose?

The DUFIX DX 175 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 175 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

• Contemporary lever profile – Unique shape differentiating it from DX 171-174

What’s the difference across the DX series (171-175)?
While the product page would confirm this, typically:

• DX 171 – Straight lever design

• DX 172 – Curved or ergonomic lever design

• DX 173 – Slim or tapered lever design

• DX 174 – Classic or traditional lever design

• DX 175 – Likely a contemporary or angular lever design with modern lines

The number change usually indicates a different lever shape, thickness, or rose size. Check the product page photos to compare.

Key Benefits of the DUFIX DX 175

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

2. Contemporary Lever Design (DX 175 Specific)

The DX 175 likely features an angular or geometric lever profile that:

• Offers bold, modern appeal – Stands out in contemporary interiors

• Provides clean lines – Complements minimalist architecture

• Features sharp details – Distinctive corners or facets

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

Applications: Where to Use the DX 175

Not recommended for: Traditional or period homes (the angular design may clash).

How to Choose Between DX 171, 172, 173, 174, and 175

Installation Overview (15-Minute DIY)

Tools needed: Phillips screwdriver only (if replacing an existing lever).

Steps:

1. Remove old lever by unscrewing the interior rose.

2. Remove the old latch from the door edge.

3. Insert the DUFIX latch – ensure the angled side faces the door frame.

4. Insert the spindle through the latch.

5. Attach the exterior rose and lever.

6. Attach the interior rose and lever, ensuring levers are horizontal.

7. Tighten screws evenly – overtightening causes sticking.
