Colombo Design Roma KSE15R: revolving brass door knob on rose

Roma KSE15R is a revolving interior door knob from the Colombo Design Antologhia collection, made of brass and supplied in a traditional round rose-mounted configuration.

Roma is one of the more substantial decorative designs in the Antologhia range. Its proportions and workmanship recall historical architectural hardware intended for important doors with strong decorative character, combining traditional manufacturing methods with extensive manual craftsmanship.

Main specifications

Revolving knob for substantial classical doors

Roma KSE15R is a revolving door knob designed to operate the lock, rather than a fixed pull knob. Its richly worked form reflects the distinctive character of the Roma series and makes it particularly suitable for substantial timber doors, classical interiors, period properties and restoration projects.

The rose-mounted configuration keeps the mounting element visually compact and allows the knob itself to remain the principal decorative feature.

Round rose and mechanical configuration

The family uses an approximately 45 mm round rose with an 8 mm spindle. Dimensions and mechanical configuration should always be checked against the actual selected version and the lock fitted to the door.

Door thickness, compatibility and rose configuration should therefore be verified before ordering.

Traditional Italian craftsmanship

Roma belongs to Colombo Design's Antologhia collection, a Made in Italy range dedicated to the reinterpretation of historic architectural hardware. Its manufacture combines traditional processes 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 methods. Such characteristics are consistent with the handcrafted character of the collection rather than the perfectly uniform appearance of fully standardised industrial production.

Natural brass and ageing

The product page offers a natural brass finish. As an unlacquered metal surface, its colour and appearance may gradually evolve through handling, exposure and natural ageing.

Natural brass gradually oxidises and develops its characteristic surface patina, contributing to the authentic appearance traditionally associated with period architectural hardware.
