Each Period Cremone Bolt by Gruppo Romi is a work of art, re-created by master craftsmen using age-old techniques to produce stunningly intricate details. This detail is simply not available in mass-produced hardware.
The central mechanisms are pictured here. Cremones are provided with rods and matching rod guides to suit any door or window.
Above is pictured a cremone of the Regency style, circa 1710-1730 from France.
