The wrench set is designed to fit around the filter housing without slipping or damaging the filter housings. The wrenches include a 1/2" square drive for use with breaker bars or socket wrenches and a 15-degree angled box end for flipping the wrench between rotations and working around obstructions near the canister. The wrench is made of 3/8" laser-cut steel with a black oxide coating for long life and ease of maintenance and has been polished and tumbled for a smooth finish. The wrenches in the set come with a limited lifetime warranty and are made in the USA.
