4x 4.5″ Cotton roller
Cotton Reel Bot Trailer Keel Rollers
Cotton reel plastic boat trailer keel rollers are similar in design to the dog bone style. Main difference in the cotton reel style include a slightly flatter centre piece with smaller tapered ends of the boat roller. This allows for boats with a flatter designed hull to be able to connect with the roller for a simply launch and retrieve at the boat ramp.
