Pro Tip: Never nail a capping rail directly onto the top of your vertical fence boards without internal support—doing so leaves air gaps that trap water and causes nails to pop out as the wood expands.

The Professional Method: Always run a flat Fencing Counter Rail horizontally right along the top back-edge of your featheredge boards first. Once your boards are sandwiched tightly against the counter rail, place this chamfered capping rail over the flat top. Drive high-torque, exterior-grade screws or hot-dipped galvanised nails vertically straight down through the thick center apex of the capping rail, passing through the board tips, and sinking deep into the counter rail below. This interlocking design will never twist or blow off in a storm!

Pro Tip: Never mount a decorative finial directly flat onto a raw post top. Trapping water between the flat base of the acorn and the post will cause both elements to rot prematurely.

The Professional Method: Always mount your acorn finial onto a matching Square Timber Post Cap/Base first. If using a dowelled version, drill a matching pilot hole into the center of the post cap. Apply a liberal coat of exterior wood adhesive or polyurethane glue to the base and dowel pin, then press it firmly into the cap. Fasten the post cap securely to the post using countersunk exterior wood screws. This dual-layered assembly creates a beautiful, multi-tiered molding effect and guarantees that rainwater runs safely away from the core joints.

Pro Tip: Metal caps fit tightly, meaning internal condensation or capillary water crawl can occasionally get trapped if the post top isn’t sealed correctly before mounting.

The Professional Method: Before sliding the metal cap over the post, coat the top 50mm of the timber post with a dedicated clear end-grain preservative. Allow it to fully dry. Next, run a generous ring of high-quality, external-grade polyurethane adhesive around the top perimeter of the wood. Push the metal cap down firmly until it seats flush. Finally, use two premium stainless steel or rust-protected black woodscrews through the pre-drilled side holes to lock it in place. The adhesive prevents the cap from shifting and stops wind-driven rain from creeping up under the metal skirt!
