This is a Coleman replacement black box latch, part 6155-510, for Coleman hard coolers and boxes. The latch holds the lid down firmly so the seal stays tight, keeping cold in and stopping the lid from popping open when the cooler is bumped or carried. A broken latch is a common failure on well-used coolers and is quick to replace. Compare the old latch's shape and mounting holes with this part before ordering. Fitment for specific cooler models could not be confirmed from the information available. It is a handy spare for anyone who uses a Coleman cooler or storage box heavily on the farm, boat or bakkie, and the black finish matches most Coleman boxes.
