Abstract
A removable access door for covering small openings in walls and ceilings includes a panel member and at least two devices for removably attaching the panel member to the structure. Each device includes a clamping member pivotally mounted adjacent a side edge of the panel and an engagement member for pivoting the clamping member from a first position that permits the clamping member to be inserted into the opening towards a second position where the clamping member extends behind an edge section of the structure. The engagement member is connected to its respective clamping member and is movable to an initial position to engage and be actuated by an edge section of the structure as the attaching device is inserted into the opening. A spring biases the attaching devices to swing the clamping members to the second position and releasably clamp the edge sections. The door can be easily removed with the use of a screwdriver inserted behind the edge of the panel.
