MOTHER-SON (UNEQUAL) DOUBLE LEAF FIRE DOORS
Also known as unequal leaf doors, this highly versatile system features one standardsized active leaf (the “mother”) for everyday pedestrian use, paired with a narrower
inactive leaf (the “son”) that remains bolted shut unless extra width is required.
KEY BENEFITS
Ultimate Flexibility: Offers standard access for people and wide access for oversized equipment in a single unit.
Energy Efficiency: Minimizes conditioned air loss by only opening the smaller active leaf during regular use.
Space Optimization: Fits perfectly into intermediate-sized wall openings where equal double doors are too wide.
IDEAL APPLICATIONS
IT server rooms, utility and mechanical rooms, service corridors, and loading bays.
