This is a Coleman replacement steel cam latch, part 6155-540, for Coleman hard coolers and boxes that use a cam-action latch to hold the lid shut. A firm latch keeps the lid sealed, which helps the cooler hold ice longer and stops the lid from opening in a moving vehicle. Steel gives more strength than a plastic latch. Compare the old latch and mounting holes before ordering, and fit with the screws or pins from the original latch where possible. Fitment for specific cooler models could not be confirmed. It is a handy spare for anyone who uses a Coleman cooler or storage box heavily on the farm, boat or bakkie.
