Abstract

A height and/or angle adjustable utility access device (10, 110, 200 or 310) includes a frame (16klk, 118, 210 or 318) secured over a utility with an opening (22) therethrough. A cover (14) is removably disposed over the opening of the frame. Height adjustment means can be disposed between the frame and the cover for adjusting the height of the cover relative to the frame. Angle adjustment means can be disposed between the frame and the cover for adjusting the angle of the cover relative to the frame. The height adjustment means can include a plurality of steps or pockets (146) foremd about a circumference of the opening at different elevations, and at elast one mating tab (150) selectively mating with at least one of the steps or pockets to selectively position the tab at a desired elevation. The angle adjustment means can include first and second angled edges (374, 378) formed between the cover and frame to selectively orient the cover with the frame.
