Abstract:
1. An access panel for an opening in a duct system, the access panel comprising: a base plate having an exterior surface side and an interior surface side, wherein the base plate is positioned against the opening of the duct system such that the interior surface side faces towards the duct system and the exterior surface side faces away from the duct system; wherein the interior surface side of the base plate has defined a first interior surface section having a profile corresponding substantially to the opening in the duct system, and a second interior surface section defined between the first interior surface section and an outside edge of the base plate, such that when the base plate is positioned against the opening of the duct system the first interior surface section resides about the opening of the duct system and the second interior surface section overlaps a duct edge defined about a periphery of the opening in the duct system; and a plurality of rotatable fasteners positioned through the base plate about the profile of the first interior surface section, each fastener having a locking clip extending from the fastener about the interior surface side of the first interior surface section and said locking clip being configured to move into a locking position, said locking position defined when the locking clip is rotated to extend over and engage the duct edge, and each fastener having a front face accessible from the exterior surface side of the base plate such that when the front face is rotated the locking clip rotates therewith; whereby when the access panel is positioned with the first interior surface section on the interior surface against the opening in the duct system and one or more of the plurality of rotatable fasteners are moved to said locking position, one or more of the locking clips rotate to extend over and engage the duct edge to secure the duct system to the base plate.
