This is a Stoltz Brand, MADE IN THE USA! Centering Keel Roller. This 5 1/2 inch Stoltz Keel Roller is made from the Highest Quality Polyurethane that has been tested and proven to outlast "poor quality" poly rollers. Anti U-V Formulas prevent rapid discoloration, and any discoloration that will occur over time is purely visual and does not effect the rollers ability to function and prevent marking, meaning this roller will hold stronger longer. Stoltz Rollers will not mark up your boat! These rollers are the real deal! Stoltz Rollers do not have a separate bushings that can come dis-lodged or dry out and crack, and the bore of the roller is sized to fit 5/8 inch diameter roller shafts. Another important thing to consider is a rusting roller shaft, which is why we have them available in Stainless Steel!
This 5 1/2 inch Stoltz Poly Keel Roller is designed to assist you in loading the boat onto the trailer, to help give you that extra push and line up your boat.
