Cathedral

KEES decorative grilles are functional works of art that pull a building’s design together. Our Cathedral pattern evokes the vaulted ceilings of medieval cathedrals, complementing your visual design while moving supply, exhaust, and return air. KEES duct access doors are easy to install and provide an economical means of access to the inside of ductwork. The fold-over tabs lock the frame into the opening. Sturdy double-wall insulated doors and gasketing prevent air leakage and heat transfer. Standard doors are suitable for low-to medium-pressure duct systems up to 4.5" w.g. while high-pressure versions are rated up to 10" w.g.
