Busiri KBU35 is a fixed door knob from the Colombo Design Antologhia collection, made of brass and featuring a substantial 110 × 110 mm frontal format.
It is the larger version of the Busiri fixed knob. Its characteristic hexagonal geometry is developed on a more substantial scale while curved transitions and rounded reliefs soften the overall form. This makes it particularly suitable for large timber doors, entrance doors and classical architectural joinery.

Busiri KBU35 takes the distinctive hexagonal form of the Busiri series and develops it into a 110 × 110 mm format. Curved transitions and rounded reliefs soften the geometric structure while preserving the recognisable historical character of the Antologhia collection.
Compared with the smaller 70 × 70 mm Busiri KBU25, the KBU35 has a much stronger visual presence and is particularly suited to large entrance doors, substantial timber doors and classical architectural joinery.
Busiri KBU35 is a fixed pull door knob: it provides a substantial grip for opening or closing the door and does not directly operate the lock mechanism.
The knob uses a single through-fixing with a 10MA threaded rod and an internal cover nut. Door thickness, structure and fixing conditions should always be checked before installation.
Busiri belongs to Colombo Design's Antologhia collection, a Made in Italy range dedicated to the reinterpretation of historic architectural hardware. Its manufacture combines traditional casting and finishing methods 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. 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 polished chrome, bronze, natural brass and natural unlacquered silver 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.
