Abstract
An access panel for an opening in a duct is provided. The access panel includes an exterior and an interior. The access panel further includes a section positioned on the interior and having a profile substantially corresponding to the opening in the duct. A plurality of fasteners is positioned about the section. Each fastener has a dip configured to move to a position defined to extend away from the profile of the section on the interior. When the access panel is positioned with the section on the interior against the opening in the duct and the fasteners are moved to the locking position the clips rotate to extend over the profile and secure a portion of the duct adjacent to the opening against the interior of the access panel.
