The Ali profiles are available in a wide range of sizes and designs, featuring base widths from 22mm to 83mm. Some profiles come with lips, while others have a flat base, ensuring you can find the perfect fit for your specific needs.

The type of hull or the surface where you apply the fender can help determine the best fendering or rub rail to choose.

Flat Side – Refers to a vertically straight surface area where fendering will be installed. Choose Wilks fendering with a flat bottom for a seamless fit.

Curved Side – Describes a hull with a vertical slope affecting the fendering installation area. Opt for profiles like “lipped” or “one-legged” to ensure secure and balanced fendering placement.

How to Install Ali Fendering?

Wilks aluminium profiles lend themselves to a simple installation process, for people of every experience level whilst also providing unparalleled elegance.

For the best results, it is recommended that two people work together to fit the aluminium profiles due to their length.

In short, to install aluminium profiles, simply attach the profile to the boat, place the insert, and add any end caps.

Installation tips: 

  • Use a pencil to mark a centre point on the aluminium length. Hold this mark against the centre of the bow and ‘roll’ the fendering body around the hull until you reach the end of the length. This gives you your first fixing point to start the installation.
  • Apply some sealant to the end of each screw before fitting to ensure that each hole is well sealed.
  • Soak the PVC insert in a tub of hot water (approx 40°C or 105°F) for around 20 minutes to make it easier to fit.



For simpler shipping and handling, Ali profiles are supplied in 3.65m lengths. However, to create the appearance of a continuous, uninterrupted length, the profiles should be joined end-to-end using a butt joint.

If trimming is required of the profile, then a hack saw is recommended. Furthermore, for a more professional and complete aesthetic pair your Aluminium rub rub with a stainless steel end cap.
