Proclassic Fire Top is a line of profiles made of AISI 316 stainless steel, designed to be used as a threshold for fire doors and all doors that require a non-combustible threshold. With a thickness of 2 mm, Proclassic Fire Top is engineered to be installed over existing flooring, whether resilient, textile, or pre-installed wood, including self-laying types, as long as they are not click-lock systems.
