The invention is concerned with a spring loaded access door which comprises a door fitting over an opening through a wall of a compartment with the door being positionable to cover the opening. Most particularly the invention is concerned with an improved means for mounting a door to a compartment such as an engine compartment whereby the door can be stably fastened in either of two stable positions, in the first of which it is spring loaded closed and in the second of which it is spring loaded open. The improved mounting means comprises a first member extending inwardly of the compartment from the wall thereof adjacent a first side of the opening having a first post extending generally perpendicularly therefrom away from said opening and generally parallel thereto; a first bracket extending inwardly of the compartment from the door adjacent and parallel to the first member on an opposite side thereof from said first post, said first bracket having a second post extending therefrom past the first member and generally parallel to, spaced latitudinally from, proceeding generally in the same direction as and generally of about equal length with the first post. Means are provided biasing the first and second posts towards one another. Also, first means pivotally couple the first bracket to the first member at a position intermediate the door and the first post to define a first and a second position for the door, the door being biased in each of the positions by the biasing means to be stably held in place, said first pivotal coupling means being located in an area defined by a first line connecting the centers of the posts in the first position, a second line connecting the centers of the posts in the second position and the door when in the first and second positions.
