Treated Timber and Outdoor Fence Post Capitals

Treated timber fence post capitals and tops that have been LOSP or H3 treated, making them suitable for outdoor use. They are available in a wide variety of designs including ball, windsor, flat and pyramid post capitals.

H3 treatment provides protection against borers and termites, moisture as well as the weather. It should never be cut or sanded, as the treatment is only applied to the exterior of the timber product. Any newly exposed timber would need to be re-treated using either a paint-on treatment or aerosol. We also recommend that all external capitals be finished with at least two coats of paint to help prevent splitting and cracking.

For more information on h3 treatment and how to care for it, see our article: What Is H3 Treatment & How To Care For H3 Treated Products. Alternatively, see the product description for more specific information on how each capital should be cared for.

Below you can sort the capitals by post size, or use the material filter in the side bar to further narrow down your search.
