I cut a rectangle hole approximately 2-1/2” x 5”, and used a flanging tool to allow the cover to sit flush. I fabricated a cover plate from 18 ga. and flanged three sides to strengthen it. The far side of the cover tucks under the floor and a self tapping screw (not yet installed) will secure the cover.
