What is a 3 piece rosette?

Our modern lever sets and deadbolts have a 3 piece rosette technology. We use a steel (not plastic!) sub rosette and the outer rosette screws on (not a clip on!) ensuring a precise grip to the door without any visible screws or holes.

  • Piece 1: Sub Rosette = The steel sub rosette has an easy assembly base and uses male/female fixing bolts to ensure a robust bolt through connection.
  • Piece 2: Inner Rosette = The inner rosette is a spring loaded plate which holds the lever for quick assembly. The modular design accommodates all lever shapes and ensures the fittings are aligned correctly.
  • Piece 3: Outer Rosette = The threaded outer rosette is screwed over the whole assembly offering a secure, safe and precise fitting. The rosette can be unscrewed when required but will not work loose in normal use.

A US size lever set vs a European size lever set

Rossette Size:

"Rosette" refers to the decorative washer connecting the knob or lever to the door.

USA the larger 2 5/8" rosette, European smaller 2 1/16" rosette.

2 5/8" rosette diameter:

US lever sets are assembled with the 2 5/8" diameter rosette; this option is ideal for pre-bore (pre-drilled) door slabs. [Example A]

2 1/16" rosette diameter:

Euro lever sets are assembled with the 2 1/16" diameter rosette; this rosette requires a smaller diameter, multi-point bore (drilling). [Example. B]

Note: Euro lever sets are also available with 2 1/16" squared rosette.

How do I clean my stainless steel modern levers?

We always say that if you clean your levers, (just like cleaning your car) you can prolong the finish and the life of the lever for as long as you own your home. We only use high quality stainless steel for our levers. recommends using stainless steel cleaner at least once a month to take off any residue that may accumulate on the levers. offers stainless steel cleaner. If you do not have any stainless steel cleaner, use hot soapy water. Please NEVER use any harsh chemicals, chlorine, bleach etc… Harsh chemicals will ruin stainless steel almost immediately.
