Extended Product Information

FAQs

Can this cap be painted or stained?

Yes, once the initial pressure treatment has fully dried, you can apply a standard exterior wood stain or paint to match your fence color.

Is this cap suitable for pressure-treated timber?

Yes, it is designed specifically for use with treated timber posts.

What is the thickness of the cap?

The cap measures 27mm in thickness, providing a sturdy profile.

Does the cap come with screws?

No, fixings are not included. We recommend using exterior-grade, stainless steel, or galvanized nails or screws.

Will this fit a standard 4x4 post?

No, a standard 4x4 post usually measures 100mm. This cap is specifically for 115mm posts.

How often should I re-treat the cap?

Depending on your climate, we recommend inspecting the wood every 12 to 24 months and applying a fresh coat of treatment if the wood appears dry.

Troubleshooting

The cap feels loose on the post

Verify the post width is exactly 115mm. If the post has shrunk due to drying, use a small amount of outdoor-rated wood filler or shims before securing.

Fasteners are causing the wood to split

Always pre-drill pilot holes using a bit slightly smaller than the diameter of your nail or screw shank to prevent timber cracking.

Water is still getting under the cap

Apply a bead of outdoor-grade silicone adhesive or waterproof wood glue between the post top and the cap before final installation.

Pros and Cons

Pros

Protects post end grains from moisture damage
Pressure-treated for long-term outdoor durability
Easy to install on standard 115mm timber posts
Enhances the overall aesthetic of garden boundaries

Cons

Requires precise measurement of post width
Natural timber finish may weather over time if not sealed
Limited to 115mm square profiles

Setup, Compatibility & Care

To install, ensure the top of your 115mm timber post is level. The cap can be secured using exterior-grade wood glue or by carefully fastening with corrosion-resistant finishing nails. Because this product is pressure-treated, it is designed for direct contact with the outdoors. Care involves routine inspection during seasonal maintenance; if you notice the wood drying out or the color fading, a fresh coat of quality exterior timber treatment will help preserve the protective properties of the cap. Always avoid using standard interior-grade fasteners to prevent rust staining on the timber surface.
