Osculati Swinging Side Roller Raised for Boat Trailers – 2, 4, 6 or 8 Rollers, Ø100/120 mm, for 40 mm Square Tube
The Osculati Swinging Side Roller Raised is a universal trailer side support assembly designed to provide elevated guidance for boat hulls during launching and retrieval. The raised bracket positions the rollers higher than standard assemblies, helping to support hulls with deeper or more pronounced side profiles while improving alignment on the trailer.
All models in this range are designed for 40 mm square trailer tubes and are available with 2, 4, 6 or 8 rollers in Ø100 mm or Ø120 mm sizes. The swinging construction allows the rollers to follow the hull contour, providing smooth support while reducing localized pressure. Rollers are replaceable for convenient servicing.
