Colombo Design Ottocento KOT11PB: brass door handle on backplate

Ottocento KOT11PB is an interior door handle from the Colombo Design Antologhia collection, made of brass and supplied in a traditional backplate-mounted configuration.

The model revisits one of the most recognisable forms of classical architectural hardware: a tapered round stem with a bell-shaped end, reproduced with proportions and manufacturing methods inspired by original 19th-century designs.

Main specifications

A classic 19th-century form

The tapered lever and bell-shaped end define the identity of the Ottocento model and directly recall the architectural hardware traditionally used on 19th-century doors. The design is more restrained than the highly decorative Antologhia models while retaining a strong historical character.

The backplate-mounted configuration creates a visually unified relationship between the lever and lock area, making Ottocento particularly suitable for traditional timber doors, period interiors, historic properties and restoration projects.

KOT11PB backplate

The KOT11PB version uses a backplate with indicative dimensions of 220 × 35 mm and an approximate C dimension of 72.5 mm. These measurements help identify the configuration and compare it with the existing door and lock arrangement.

The selected version, keyhole configuration and required lock dimensions should always be checked before ordering.

Traditional Italian craftsmanship

Ottocento belongs to Colombo Design's Antologhia collection, a Made in Italy range inspired by historic architectural hardware. Traditional manufacturing methods are combined with a significant element of manual craftsmanship and hand finishing.

Slight porosity, texture or minor surface variations may occur as a natural consequence of these traditional processes and are consistent with the handcrafted character of the collection rather than the perfectly uniform appearance of fully standardised industrial production.

Natural finishes and ageing

The product page offers bronze, natural brass and natural unlacquered silver finishes. Unprotected metal surfaces may gradually change in colour and appearance through handling, exposure and natural ageing.

Natural unlacquered brass, in particular, gradually oxidises and develops its characteristic surface patina, contributing to the authentic appearance associated with traditional architectural hardware.
