SLIM Rosettes 5mm vs 7mm – What Is the Difference and Which One Should You Choose?

What is a SLIM rosette?

A SLIM rosette is the round plate that sits in the recess machined into the door. The SLIM designation indicates that the rosette is recessed into the door rather than surface-mounted.

5mm SLIM rosette

• Fits recesses 5mm deep
• Suited to modern doors with a shallow machined recess
• The rosette sits perfectly flush with the door surface
• Most commonly used on lacquered HDF and MDF doors

7mm SLIM rosette

• Fits recesses 7mm deep
• Suited to doors with a deeper recess or solid wood
• Firmer fixing, recommended for heavy use

How do you measure your door's recess?

1. Remove the existing handle
2. Measure the depth of the recess in the door surface
3. 4.5 – 5.5mm -> choose SLIM 5mm
4. 6.5 – 7.5mm -> choose SLIM 7mm

What happens if you choose the wrong thickness?

• Rosette too thin: it sits sunken, leaves a visible gap and does not fix firmly
• Rosette too thick: it stands proud, looks unsightly, and forcing the fit can damage the door

What a SLIM rosette is and why there are two thicknesses

The rosette is the piece that covers the opening in the door around the locking cylinder. The SLIM rosette is a low-profile alternative to the classic rosette (which can reach 12-15mm in thickness), designed for modern doors with a minimalist look.

Enger's APRILE collection offers SLIM rosettes in two thicknesses: 5mm and 7mm. The difference sounds small, but it has important practical consequences for compatibility with your door.

The rosette's thickness determines how much of the door surface it covers around the cylinder. A thicker rosette conceals imperfections and larger openings better, but stands further proud of the door surface.

When to choose the SLIM 5mm rosette

The 5mm rosette is the right choice in these situations:

• Modern doors with an HPL or laminate finish — the flat, smooth surface lets the rosette integrate perfectly
• Doors lacquered in white or matte black — the ultra-flat design complements the minimalist aesthetic
• Architectural projects where details matter — the 2mm difference shows in interior photography
• Low-profile cylinders — when the cylinder does not protrude beyond the door surface
• Renovations where the original opening is clean — if the edges of the opening are precise, 5mm is enough

When to choose the SLIM 7mm rosette

The 7mm rosette is more versatile and suits a wider range of situations:

• Solid wood or MDF doors — the material may show slight irregularities around the cylinder
• Replacing an old rosette — the original opening may be slightly larger, and 7mm covers it better
• Standard cylinders with a slightly protruding head — the extra thickness creates a more balanced visual effect
• Classic or semi-modern doors — the more generous proportions are a better match

How to measure correctly before ordering

Before ordering SLIM rosettes, check these dimensions on your door: (1) The PZ centre distance — from the centre of the cylinder to the centre of the handle, 72mm standard. (2) The cylinder type — is the head recessed, or does it protrude 2-3mm? If it protrudes, go for 7mm. (3) The opening diameter — 28-30mm standard. If it is larger, choose 7mm. (4) The locking type — OB, PZ, WC or BB. The rosette must match the cylinder type.
