Direct answer
To measure a replacement dock fender, first identify the end-view profile, then record the complete cross-section, overall length, internal bore or cavity, mounting-hole diameter and spacing, hole count, installation direction and available mounting space. Add overview, end-view and fixing photographs before sending the RFQ.

- Identify the application and visible profile
- Record dimensions and mounting details
- Attach drawings, photographs and quantity
- Confirm final requirements in writing

Seven measurement steps
| 1. Photograph the location | Show the berth, contact direction, adjacent structure and complete existing fender |
|---|---|
| 2. Record the end profile | Take a square-on end photograph and sketch the outside and internal shape |
| 3. Measure the cross-section | Record maximum width, height, diameter and cavity or bore dimensions |
| 4. Measure the length | Record the complete piece length and any damaged or cut end |
| 5. Record the holes | Measure diameter, centre-to-centre spacing, count, direction and edge distances |
| 6. Check the mounting surface | Record plate, concrete, timber or steel support and any limited access |
| 7. Add project data | State quantity, application, project location and required schedule |

Photographs that make identification easier
- A wide view showing where the fender is installed
- A full-length view parallel to the fender
- A square-on end view without strong perspective distortion
- Close-ups of holes, fasteners, damage and the mounting surface
- A ruler, tape or marked sketch showing the measurement points

How to handle a worn or damaged sample
Do not measure only the most damaged area. Take several readings and mark where wear, permanent deformation or missing material affects the result.
If available, compare another less-worn fender, the original project drawing or an unused sample. State clearly which dimensions were measured and which came from documents.
A supplier review does not replace approval by the project owner or responsible designer when performance requirements or structural changes are involved.
Frequently asked questions
How to Measure a Replacement Dock Fender FAQ
01Can I measure a dock fender while it is installed?＋
Yes for an initial review if the area is safe and accessible, but hidden dimensions and compressed areas may require a drawing, removed sample or additional inspection.
02How should hole spacing be measured?＋
Measure from the centre of one hole to the centre of the next, and also record hole diameter, number, direction and edge distance.
03What if the old fender has no drawing?＋
Prepare an end-view sketch, measurement table and complete photo set. A physical sample may be needed before final confirmation.
04Can the replacement be ordered directly from website information?＋
No. Website guidance helps prepare the inquiry; the final drawing and written order specification must be confirmed separately.
