The puncture-resistant polyethylene float is foam filled for years of maintenance-free service. When mounted on the float, the strainer box may be locked in place to prevent banging against carrier's legs. The strainer box can be easily detached, even with a gloved hand, for use as a box strainer or for storage. The box strainer is more efficient than a barrel strainer and it may be left attached to the hard sleeve.
