Abstract
A duct access door for use with ducts that carry cooking vapors and greases is a “sandwich” type door that has inner and outer plates, the inner plate being positioned inside the duct and the outer plate outside the duct with a heat resistant gasket attached to the outer plate. Strategically located bolts draw the plates together at their corners to provide compression of the gasket and prevent leaking of vapors and greases.
