Description

The CONE Lever Handle 100-G by Formani is a rosetteless door lever with the distinctive conical neck tapering to the handle. The rosette-less design creates the illusion of a floating door handle. Manufactured as one piece — a technical masterpiece with seamless joints.

Part of the CONE collection, designed by Osiris Hertman for Formani. Inspired by the hardware on a bank safe — secure, complete, and rooted in simple functionality. The tapered conical neck creates clean lines and a distinctive shape. Winner of the 2021 Red Dot Design Award in Product Design.

Additional Components
Specifications
  • Ø 50 mm (1.9") x L 131 mm (5.1") x H 65 mm (2.5")

European roses are smaller than standard North American models. Verify all dimensions carefully — these may not fit existing or pre-bored door holes.

Materials

Available Finishes

  • Satin Stainless Steel
  • PVD Satin Black

PVD finishes bond to the metal surface, creating a layer that improves durability, corrosion resistance, and long-term appearance. PVD is suitable for exterior and coastal applications where available.

Ordering Guide

Formani levers are sold as components and built to order. To prepare your quote, please confirm:

  • Function — select one:
    • Passage — interior doors that latch but do not lock (hallways, closets, pantries)
    • Privacy — doors that lock from one side with a thumb turn and emergency release (bathrooms, bedrooms)
    • Keyed Entry — exterior or secured doors operated by a key cylinder on one side and a thumb turn on the other
    • Dummy — non-operating decorative lever for fixed panels or inactive leaves of double doors
  • Backset — 60 mm standard for euro mortise
  • Door thickness — measured at the lock case
  • Door condition — must not be pre-bored

Formani door hardware pairs with the d line heavy-duty euro mortise lock & latch. Privacy configurations require a thumb turn; keyed entry requires a CES key cylinder with matching escutcheons.

Finish Samples

Dutch precision, designed.

Formani is a Dutch hardware manufacturer producing lever handles, escutcheons, cabinet pulls, and bathroom accessories. Founded in the Netherlands, the company works with a focused group of designers — among them Piet Boon, Bertram Beerbaum, Osiris Hertman, Edward van Vliet, and the office of Gensler — each briefed to develop a total concept rather than a single product.

The result is a catalogue of coordinated systems that move across doors, windows, furniture, and bathrooms without visual interruption. Finishes — including satin stainless steel, PVD satin black, bronze, PVD satin gold, and polished stainless steel — are shared across collections, so a lever, a cabinet pull, and a towel bar can arrive at a project from the same material palette.

Every piece is precision-welded in the Netherlands and designed to work with both European mortise and North American tubular latch systems. Formani hardware is built to sit flush, return cleanly, and remain legible at the scale of a room.

Principles

01

Complete Concepts
Each Formani collection spans door levers, escutcheons, cabinet hardware, and bathroom accessories — one design language across every contact point in a space.

02

Designer Collaborations
Collections are developed with named designers including Piet Boon, Bertram Beerbaum, Osiris Hertman, and Gensler, each producing a coherent formal system rather than individual objects.

03

Finish Consistency
All finishes — satin stainless steel, PVD satin black, bronze, PVD satin gold, and polished variants — are available across collections, enabling a unified material palette on a single project.

04

Dual Compatability
Hardware is engineered for both European mortise and North American tubular latch configurations, with explicit backset and door-thickness specifications provided for every product.
