Installation Instructions


What is a backset?


"Backset" refers to the distance from the center of the bore (drilling) to the edge of the door. Both US and Euro lever sets are available with either a 2 3/8" backset (standard) or 2 3/4" backset.

NOTE: Backset dimension MUST be specified.

Example A:


What is a strike plate?


"Strike Plate" refers to the decorative jamb mounted receiver where the latch first makes contact.

Both US and Euro lever sets are provided with a "T- Strike" (standard)

NOTE: a "Lip Strike" may be substituted for Both US and Euro lever sets.

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.

Select from the larger 2 5/8" (UER) rosette 

2 5/8" (UER) rosette:

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.


What do the terms Passage (PAS), Privacy (PRI), and Dummy (DUM) mean?


Both US and Euro lever sets are available as "Passage", "Privacy", or Dummy.

    The sound of the door shutting will tell you a lot about the solid product you have. And the looks, another win.

    Perfect handles for our modern home

    I didn't plan to change all the door handles in our home when we started our addition and remodel. When I saw the Manhattan lever handles online, I knew I wanted them everywhere in our house. I started with an order of just a couple handles to check out the quality. These are well designed, solid handles that should last forever. We even replaced some exterior door handles with the passage levers and deadbolt. These handles coordinate well with an Anderson satin nickel lever handle, so now everything match. I highly recommend these German made stainless steel lever handles.

    Very elegant and great finishing touch to my condo

    This past year I did a major upgrade to my entire condo. Put the Manhattan style handles/levers on the three exterior French double-doors, an exterior closet door on the terrace, and the condo front door with the matching lock. The style exactly matches the interior handles I had already installed (Modernus by Nova). The levers are elegant, beautiful, feel very sturdy and seem like they will last forever. I love the feel of them every time I walk in and out my front door. Very solid. Even love the keys that come with them. The head was large enough I was able to have my initials stamped in them. Great workmanship all around. Definitely would recommend.

    Good materials, good design, manufacturing OK

    Hollow stainless lever which should last forever. Welds look good. Issues: 1.) Outside lever and inside lever are not level with each other. I picked the outside lever to be level which in turn made the inside lever approx 5 degrees off. 2.) Machining where the lever meets the rose was slightly out of flat. There was a slight rock in the lever which I corrected with 1/32" thick self adhesive gasket material. 3.) Template was off. When you fold over the door edge it shows that you should drill the edge below the centerline of the lockset. This is incorrect! Ignore the template! Latch hole should be drilled at same level as the lockset holes. In summary, the design of the piece is first class, the pricing is competitive, and the materials are first class. The manufacturing quality is subpar though.
