ABSTRACT:
A hollow aluminum pole has access to its interior through a hand hole frame having an access aperture which can be blocked by a cover having a lower end pivotally attached to the hand hole frame by a pivot pin. The pivot pin is biased inwardly by a coil spring which permits outward movement of the cover to a position in which it can be rotated downwardly out of alignment with the access opening.
