8” PARALLEL / FLAT BOAT TRAILER KEEL ROLLER
PARALLEL / FLAT BOAT TRAILER KEEL ROLLER
Parallel or flat styled boat trailer keel rollers are generally designed for medium to larger sized boats. With the thicker material and profile, the roller is designed to be able to hold slightly more weight than other rollers. Parallel keel rollers are a great roller to use in conjunction with our boat trailer bunks and flipper systems.
