ABSTRACT:
A keeper is disclosed for releasable attachment to a chain in order to support a gathered length of the chain at a safe, yet accessible overhead location above the ground surface. The keeper includes a tubular body which can be used to accumulate a length of chain. A finger at an upward, open end of the body may be releasably hooked between openings of adjacent links of the chain in order to suspend the keeper and the accumulated chain length at the selected elevation. The finger is preferably resilient or, alternatively, pivotal to facilitate disengagement of the keeper from the chain by simply pulling downwardly on the keeper handle. The keeper may be completely removed from the chain by pulling forcibly downward on the keeper to disengage the finger from the chain and allow the keeper and chain to move downwardly to the point where the keeper becomes completely disengaged from the chain.
