Abstract: An apparatus is arranged relative to a port or line to suspend the apparatus and effect leveling of the associated line. The apparatus includes a housing, with a top wall defined by an elongate opening, with a liquid level member positioned within the housing. The top wall further includes a first and second slot to each side of the housing, with each slot mounting hook members that are normally biased together to define an enclosed loop and are biased apart to a second position for opening relative to the line to effect mounting of the housing to the line.
