The Profi RP335 roller 71x76 mm, with a bushing diameter of 13.5 mm, made of yellow polyurethane, is used on trailers that transport heavy motorboats and oversized yachts. Smooth and exceptionally durable, the Profi roller securely holds the boat, protecting the sides and bottom from mechanical damage. This type of roller is recommended to be installed at the rear of the trailer as a guide roller, at the front as a bow stop, or underneath the keel of the vessel.
