Description
Post Acorn Finial Green Treated – Decorative Timber Fence & Gate Topper
Overview
Standard flat or pyramid caps are great for utility, but your primary property boundaries—like front garden gates, driveway entryways, and main decorative pergolas—deserve a more sophisticated finish. Our Green Treated Timber Acorn Finial completely transforms plain, industrial-looking square posts into traditional architectural statements. Inspired by classic English estate designs, the acorn motif symbolizes strength and longevity, making it the perfect finishing touch for a stately home exterior.
Milled from premium softwood, each finial is chosen for its tight grain structure, ensuring the intricate turned curves hold their shape beautifully against seasonal frost and intense summer sun. Because the piece is deep pressure-treated, the protective barrier reaches right into the core of the turned design, bypassing the need for immediate surface painting or staining.
Key Features
-
Instant Premium Accenting: Drastically upgrades standard closeboard, panel, or palisade fence layouts with a distinct craftsman look.
-
Superior Water-Shedding Form: The aerodynamic, multi-tiered turned pattern leaves no flat surfaces for rainwater to pool, keeping the joint dry.
-
Sustainably Sourced Softwood: Milled entirely from responsibly managed forests, delivering high strength with an environmentally conscious footprint.
-
Flexible Aesthetic Finish: The soft green-treated tint matures naturally over time into a warm honey-brown before weathering to a classic silver-grey. It serves as an excellent canvas for exterior paints or wood stains to match your layout.

Trade Installation & Fitting Tip
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.
