A timber fence needs a cap that fits its construction, not simply its overall length. The timber capping profiles in this category form the top detail; their section dimensions determine how they sit over the boards and meet the posts. Fence battens that extend to the upper edge need their depth allowed for when checking the fit. Corners and stepped sections also need joint details that suit the chosen profile.

Fence Capping

New Zealand fencing projects need a fence capping rail specified for outdoor exposure and compatibility with its fixings. Confirm the timber’s treatment and coating requirements in the product information rather than judging suitability by appearance. Long runs need particular care at joins: plan where each length ends and how it will be supported. Gate openings need a separate check so the cap does not obstruct the gate’s movement or hardware.

Can capping be added to an existing fence?

Check the top boards and supporting rails for decay or loose fixings before fitting a cap. Repair those areas first, then measure the full run, including changes in level.

How is trellis capping different from a cap for fence boards?

A trellis cap must suit the panel’s frame and lattice arrangement rather than the thickness of a row of boards. Check the profile drawing and fixing requirements instead of assuming the two are interchangeable.

Should the underside be coated before installation?

Follow the timber and coating supplier’s instructions for faces that will become inaccessible after fixing. Treat cut ends as specified and allow any required drying time before assembly.
