4-foot roller bunks (pair) attach directly to vertically-mounted 2 x 4 bunk boards, or can be mounted with 6356 brackets (sold separately). A quick, easy and inexpensive way to upgrade bunk trailers to rollers. 14 gauge steel, black powder coated finish, rubber rollers. For boats weighing up to 2500 lbs. The advantage of this style of roller bunks is that each set of rollers has some wobble capabilities (up to roughly 10 degrees), providing some self-alignment with the boat hull. The rated capacity is based on having good contact with all of the rollers, and a reasonably even distribution of weight on the rollers. Rollers must be in contact with straight sections of the boat hull. It is critical to avoid a very large load on the first set of rollers during the unloading and loading process. The boat should float at least part way onto the trailer before contacting rollers, so that all of its weight is not concentrated on the first set of rollers. A concentrated load can crush a single set of rollers, with the potential for damage to the boat hull.
