Siena KSI11P is an interior door handle from the Colombo Design Antologhia collection, made of brass and supplied in a traditional backplate-mounted configuration.
Siena revisits one of the most recognisable forms of classical architectural hardware: a cylindrical stem ending in a bell-shaped terminal. The design is restrained yet clearly rooted in historical door hardware, making it particularly suitable for timber doors, period interiors and restoration projects.

The lever profile is the defining feature of the Siena model. Its cylindrical stem terminates in a bell-shaped element that directly recalls historic architectural hardware while avoiding excessive decorative complexity.
The backplate-mounted configuration creates a visually coherent relationship between the lever and lock area, making Siena particularly suitable for classical timber doors, traditional interiors and restoration projects.
For the Siena backplate configuration, the Antologhia catalogue indicates approximate dimensions of 225 × 32 mm, with an indicative C dimension of 75 mm. These measurements should be checked against the actual selected version and lock arrangement before installation.
Siena belongs to Colombo Design's Antologhia collection, a Made in Italy range dedicated to the reinterpretation of 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 processes. Such characteristics are consistent with the handcrafted character of the collection rather than the perfectly uniform appearance of fully standardised industrial production.
The product page offers bronze, natural brass and natural nickel finishes. Natural untreated metal surfaces may gradually change in colour and appearance through handling, exposure and ageing.
Natural unlacquered brass, in particular, gradually oxidises and develops its characteristic surface patina, contributing to the authentic appearance associated with traditional architectural hardware.
The product page includes different backplate configurations according to the lock specification. Before ordering, the keyhole type, centre distance and required door dimensions should therefore be checked carefully.
