SCENE 02 · THE RATING

Twenty. Sixty. Ninety.

Minutes the leaf holds the line — chosen per project, certified per leaf. UL 10B / UL 10C / NFPA 252 endurance, hose stream included. Your specifier picks the number; the furnace has already agreed.

SCENE 03 · THE PROOF · UL 10C / ASTM E119

25°C

ELAPSED · 000 MIN

The standard curve, traced by your scroll — past 900°C at minute ninety, held to the end of the run. Then the door is measured again, on the cold face.

One purchase order, one delivery, one installer interface: flush light-oak leaf, stepped frame, factory-fitted ironmongery. Underneath the calm face sits the full rating matrix — 0.5, 1.0 and 1.5 hours, certified and current.
