A utility access device and method includes telescoping, elongated upper and lower sleeves with an inclined upper edge. An angled ring is rotatably disposed on the inclined upper edge and has upper and lower opposite edges forming an inclined angle. The angled ring can be rotated to achieve a desired angle. A cover is removably disposed on the angled ring. An enlarged portion can be formed on the lower sleeve to straddle a utility, such as a valve.
