Olivari conceived the Diana as one of its studies using square geometrical forms. It is a versatile archetype thanks to its wide frontal surface, which lends itself to experimenting with the application of decorations.


Lever Passage door handles with latch are designed for internal doors. The lever passage set includes all fittings (tie through screws, spindle, and latch).  This passage set can be used on an external door with a separate lock or deadbolt. 


Powder coating is an option. Please discuss with our sales team.
