Donut Fender Introduction
Donut fender is suitable for the places like lock entrances, turning structures, approach channels, and breasting dolphins. It's often installed on the surface of the quay wall and can rise and fall with the tide. Apart from the feature of tide adaptation, this donut fender can also rotate around the pile helping guiding vessels due to its low friction. Donut fender shares the same high-quality raw material and similar construction with foam filled fender, and it's unsinkable, easy to replace and maintain. Jerryborg can offer various donut fenders in different sizes and colors upon the customer's request.

Donut Fender Installation
The installation of donut fender is very simple. All we have to do is to deliver the fenders to the site and lift over and lower them onto the fender pile. We don't need to ballast or trim the fenders cause they'll float at the level that is already designed. The last step is to place the capping part over the top of the fender pile. Jerryborg offers donut fenders with various sizes and colors with a long lifespan, besides they're easy to maintain and cost-effective.
