Currently, doors on the market all have the same problem in that they are mounted at the plane of the duct, and extension rods, Insulation layers, and cover plates are then added. The problem is, all these need to be removed to access the duct for cleaning. Easy Access grease duct door solves this by having an insulated frame and allowing the hinged door to open at the plane of the wrapped system. A fail proof system, with nothing to remove, drop, set aside, avoiding incorrect re-install. Just open, clean, and close!
