Abstract: An adapter for facilitating an easy and secure connection between a sewage drainpipe and a sewage disposal inlet. The adapter includes a tubular member, at least one connection lug, a ring, and at least one flange. The tubular member forms a channel defining an inlet and an outlet, the outlet insertable into the sewage disposal site inlet. At least one flange extends from an outer surface of the tubular member to increase an outer circumference of the tubular member to allow the adapter to facilitate a rapid and secure frictional connection with the sewage disposal site inlet. The flanges are configured to form a stepped configuration so the adapter may securely fit into a variety of disposal site inlet sizes. The ring, typically disposed above the flanges, includes a threaded portion, and is configured to thread onto a predetermined sewage disposal site inlet size to form a substantially leak-free seal.

Abstract: A leveling block set with a handle, leveling blocks, and a receiver for leveling a large vehicle like a camper or trailer. Each leveling block has a top surface, sidewall, bottom surface, and a void defined by the sidewall and bottom surface. An opening in the top surface creates a channel that accepts and retains a portion of the receiver and the handle. The receiver has a base and shank with a passageway forming a second engagement member. The handle has a grip and shaft with a first engagement member. The shaft can be inserted through the channel to mechanically engage with the second engagement member of the receiver. The receiver is secured in the channel by two shoulders formed in the channel. If the receiver is lost or damaged, a replacement can be inserted without replacing the leveling blocks.
