What are Rubber D Fenders used for?

A fender is another term for a 'bumper', or a protective piece of rubber that is mounted on a mobile vehicle of some kind in order to protect it in the event that it bumps into something. Rubber D Fenders are designed to absorb the kinetic energy produced in a collision.

D Fenders are shaped like the letter ‘D’. They are the most popular style of rubber bumper used globally and can be manufactured by extrusion in a range of sizes and styles. The ‘D’ shape creates a flat section that is used to make installation easier.

Aquaseal Rubber produces fenders for boats, docks, loading bays and vehicles primarily, but we also produce the bumpers for Royal Mail warehouse trolleys! Such a unique product gets a lot of wear, but we are capable of producing rubber D Fenders of all shapes, sizes, and order quantities.

What types of Rubber D fenders are there?

There are three main types of D fender.

  • DD Fenders have D shaped inner chambers, allowing for maximum compression
  • DC Fenders have O shaped inner chambers, allowing for medium compression
  • Solid D Fenders have no inner chamber and allow for minimal compression

Depending on your application you might need a bespoke D Fender. Speak to a member of the Aquaseal team to discuss your specifications.

What processes are used to manufacture Rubber D Fenders?

We produce D Fenders through a die, using a traditional extrusion method. They can also be pre-drilled, pre-curved, chamfered, and cut to specific lengths in order to assist the requirements of your unique application.

Rubber D Fenders can be installed using bolts and strips – either diagonally, horizontally, or vertically. When we produce Rubber D Fenders, we can pre-drill mounting holes into the sides or tops and bottoms of the fender in order to make the fitting process simpler.

Which applications use Rubber D Fenders?

You’ll find Rubber D Fenders used most commonly in the marine industry, as well as the warehousing, loading dock, and loading bay industries.

They’ve become increasingly popular thanks to the fantastic level of protection offered across a wide range of applications, including:

  • Tugboats
  • Workboats
  • Pilot boats
  • Fishing boats
  • Pontoons
  • Quays
  • Piers
  • Jetties
  • Loading Bays
  • Car Parks
  • Trucks and Lorries
