Colombo Design Busiri KBU12 / KBU12B: brass window cremone handle

Busiri KBU12 / KBU12B is the traditional window cremone handle from the Colombo Design Antologhia collection, made of brass and available in two configurations: KBU12 with high plate and KBU12B with low-profile plate.

The Busiri design is based on a distinctive hexagonal-inspired geometry softened by curved lines and rounded reliefs. Both versions retain the same design language but differ in plate construction and overall dimensions.

Main specifications

KBU12 with high plate

The KBU12 version uses the traditional high plate and measures approximately 150 mm high, 40 mm wide and 60.5 mm deep.

KBU12B with low-profile plate

The KBU12B version uses a low-profile plate and measures approximately 152 × 36 × 51 mm. In this configuration, the internal mechanism must be recessed into the window frame.

Cremone mechanism

The internal mechanism is not included and must be selected separately according to the window hardware and construction.

The handle set includes the cremone handle, fixing grub screw and hex key.

This product page covers the traditional KBU12 and KBU12B cremone handles. Versions intended for tilt-and-turn / Dreh-Kipp windows should be treated as separate products.

The Busiri design

Busiri interprets traditional architectural hardware through a hexagonal-inspired geometry softened by curved transitions and rounded reliefs. The cremone handle can therefore be coordinated with Busiri door handles, knobs and other fittings from the same family.

Traditional Italian craftsmanship

Busiri belongs to Colombo Design's Antologhia collection, a Made in Italy range manufactured using traditional brass-working methods with a significant element of manual craftsmanship and hand finishing.

Slight porosity, texture or minor surface variations may occur as a consequence of these traditional manufacturing methods and are consistent with the character of the collection.

Natural finishes

The product page offers bronze, natural brass and natural unlacquered silver.

Natural untreated metal surfaces may gradually change through handling and ageing. Natural unlacquered brass, in particular, oxidises over time and develops its characteristic surface patina.
