The Colombo Design Ellesse BD21 RSB/0, designed by Bartoli Design, is a pair of Cromall® interior door levers featuring the Zero Evolution system. Its straight grip and minimal square mounting base create a restrained architectural appearance defined by precise geometry and reduced visual bulk.
Ellesse reflects contemporary design through sharp geometric forms, regular surfaces and balanced proportions. The horizontal lever connects to its square mounting base through a clean, angular transition, creating a consistent composition without unnecessary decoration.
Colombo Design describes Ellesse as a handle whose precise, angular lines bring order and sophistication to interior spaces, expressing the character of modern architectural design.
The BD21 RSB/0 uses the Zero Evolution system, with a minimal mounting base that reduces the visible presence of traditional door hardware. The lever pair operates a compatible interior door lock.
