发明名称 Shroud for septic tank access opening
摘要 A shroud for use in combination with a septic tank having an access opening and an access cover. The shroud surrounds the access opening and facilitates removal of the access cover covering the access opening and providing access to the septic tank. The shroud comprises a contiguous sidewall opened at first and second opposed ends thereof with an access passageway extending therebetween. A first open end of the shroud has an annular surface for abutting engagement with a top surface of a septic tank. A retaining member retains the annular surface, at the first end of the shroud, in abutting engagement with the top surface of the septic tank. A removable shroud cover seals the second open end of the shroud and the shroud cover, when removed from the second end of the shroud, facilitates access an interior cavity of the septic tank.
