Keyhole fenders ribbed information:

Keyhole fenders are used worldwide and they offer very reliable protection for the bow of a vessel or for the wall of a quay. This type of fender is characterised by the keyhole-shaped opening on the inside and it is used in areas where large forces must be absorbed. Keyhole fenders are strong and they can be produced with a curve. The two mounting holes facilitate easy and accurate installation.

Types

Standard keyhole fenders are produced by length or as a block and they are made from highly wear-resistant rubber. Lengths are produced by means of extrusion and blocks by means of compression-moulding. Keyhole fenders are produced with a flat face or a grooved face, depending on the friction and/or grip required. As with the composition fender, this type of fender can also be produced with an UHMW-PE surface layer. FenderTec keeps most standard sizes in stock for fast delivery. Custom sizes can also be supplied on request with short lead times. Keyhole fenders, V fenders and M fenders are not interchangeable.

Processing

Keyhole fenders are relatively easy to install. In general they are mounted vertically with fixing pins through the two standard holes. Keyhole fenders can be provided in specified lengths and the ends can be bevelled if required. If the fenders are longer than one meter an opening for a support strip can be added.

Applications

Keyhole fenders are widely used in various sizes and designs on:

  • Tugboats
  • Barges
  • Workboats
  • Quays
  • Piers
  • Bridge sections

FAQ

What is a Keyhole fender?

A Keyhole fender is a marine fender designed with a keyhole-shaped opening to engage a mounting post or pin. It is a rubber or elastomeric component used to absorb and distribute impact energy between a vessel and a berth, vessel and vessel, or between pushing units and pushed units. Keyhole fenders are used where a secure, low-profile attachment is required to keep the fender aligned during berthing and manoeuvring operations.

What are Keyhole fenders used for?

Keyhole fenders are used to protect hulls, berthing structures and pushing interfaces by absorbing impact energy and reducing localized loads. They are commonly applied on tugboats and as pushing stern fenders where repeated contact occurs between vessels. The fenders help to prevent structural damage, reduce shock transmission and provide a resilient contact surface during mooring, towing and ship-to-ship operations. Contact our team for technical advice on selecting the appropriate fender type for a given application.

What is a ribbed Keyhole fender?

A ribbed Keyhole fender incorporates longitudinal or circumferential ribs on its contact face to improve grip and wear characteristics. The ribbed profile can reduce sliding during contact, increase surface area for energy distribution and assist in channelling water and debris away from the contact zone. Ribbed Keyhole fenders are chosen where enhanced abrasion resistance and controlled contact behaviour are required. For guidance on whether a ribbed profile suits your vessel or structure, consult our technical team.

How are Keyhole fenders installed?

Keyhole fenders are installed by engaging the keyhole opening onto a compatible mounting pin, boss or rail system designed to retain the fender under load. Proper installation requires a matching mounting geometry, adequate backing structure and secure fastenings to prevent displacement during operations. After installation, regular inspection and maintenance are recommended to verify attachment integrity and material condition. For installation recommendations and compatibility checks, please contact our team for technical assistance.
