The Siena KSI12 DK/SM is a brass tilt-and-turn window handle from the Antologhia collection by Colombo Design. It features a shaped vertical grip with a decorative bell-shaped end, mounted on a 65 × 31 mm oval backplate.
The DK/SM configuration is designed for DK / Dreh-Kipp (tilt-and-turn) window systems. It differs from the traditional Siena KSI12 and KSI12B cremone handles, which feature a double-ended turning grip and an elongated backplate.
The Siena design draws on traditional architectural hardware, combining a shaped brass grip, decorative mouldings and a distinctive bell-shaped terminal. The DK/SM version retains the collection's classical appearance in a configuration intended for tilt-and-turn windows.
Made in Italy using traditional brass-working methods, the Antologhia collection incorporates a significant element of manual craftsmanship and hand finishing.

Dimensions are taken from the manufacturer's technical drawing for the KSI12 DK/SM. The overall height of 140.5 mm must be distinguished from the 65 mm height of the mounting backplate.
The Siena KSI12 DK/SM can be ordered in three standard finishes:
Natural unlacquered finishes may gradually change in appearance through handling and ageing. Minor porosity or surface irregularities may be consistent with the traditional brass-working and hand-finishing processes employed in the Antologhia collection.
The KSI12 DK/SM window handle is supplied without the operating mechanism, which must be selected separately according to the window hardware. Check mounting dimensions, window frame preparation and tilt-and-turn mechanism requirements before ordering. Matteoda customer service can assist with mechanism selection and estimated ordering lead times.
