Product Description

Inflatable Dock Bumpers Monopile Donut Fender Foam Fenders For Boats 
The Donut Fender is a specialized foam fender designed to slip over stationary monopiles and float freely around a pile. This unique design maintains consistent positioning in water, even with extreme tidal fluctuations, making it an effective solution for berthing dolphins, guiding structures, and turning applications.
Constructed to float up and down single tubular piles with changing water levels, the fender freely rotates to help align or redirect vessels during berthing. When used as a turning dolphin, donut fenders guide vessels in challenging berthing situations by rotating under compression.
Key Construction Features:
  • 100% closed-cell cross-linked foam core - Unsinkable and resistant to bursting or deflation
  • Internal steel core with durable UHMW bearing pads for minimal maintenance
  • Polyurethane elastomer skin reinforced with continuous nylon filaments for maximum durability
  • Customizable dimensions - Available in diameters from 1,270mm to 4,220mm with pile diameters from 610mm to 2,388mm
Floating Monopile Donut Foam Fender Features
Inflatable Dock Bumpers Monopile Donut Fender Foam Fenders For Boats 0
Tough Outer Skin
Donut fenders feature a rugged polyurethane elastomer outer skin designed to prevent snagging on hull protrusions or dock fittings. The thick skin is reinforced with nylon for added strength and durability.
High Energy Absorption Foam Core
The high-performance closed-cell foam core, combined with our specialized laminating process, ensures structural integrity and optimal energy absorption in every fender.
Inner Steel Tube
The central steel tube resists mooring loads while providing a stable, non-abrasive core for the foam body. This precision-engineered component is manufactured to exact specifications.
UHMW PE Pads
The low-friction UHMW bearing pads require minimal maintenance while allowing the float to rotate freely around piles and adjust to changing water levels.
