Abstract: An insertable clean out sleeve for use with a matching receiving cylinder or an existing receiving cylinder. The clean out sleeve is sized to fit within the receiving cylinder and to be easily placed within the receiving cylinder and easily removed from the receiving cylinder. Debris which would otherwise fall into the receiving cylinder, ultimately clogging it, will fall within the clean out sleeve. The clean out sleeve may be removed from the receiving cylinder and emptied of debris and reinserted into the receiving cylinder. This means that a vertical center rod used as part of the closure and/or locking system on an existing gate for a fence will be easily used without concern that debris may clog the receiving cylinder.
