Donut Fenders (SZ-D Fender)

SZ-D Fender(Donut Fender) is a ring-shaped, foam filled fender designed to be installed onto poles and rises and falls with water levels.

It’s core is a central steel monopole and is guided by a low-friction UHMW-PE pad. It rotates freely, so that friction is reduced between the fender and the vessel, allowing the vessel to slide along the donut fender, rater than rubbing against it.

Features
  • Energy absorbing foam core
  • Heavy-duty, internal steel core
  • Rise and fall with tide fluctuation
  • Anti-friction bearing UHMW-PE pad
  • Free rotation
