About this lumber

What you’re buying.

The 10 ft 4×4 fence post, a true 3½ in. square, and the post a 6 ft fence in southern Ontario needs: 48 in. in the ground to clear frost and 6 ft standing above grade. An 8 ft post set that deep stands 4 ft, so it is the post for a 4 ft fence, not a 6 ft one. Ground-contact treated, the heavier treatment a fence board does not need, because the post is the one piece that lives in the soil.

One post per 8 ft section, plus one to close the run, at 96 in. on centre, for a stick-built fence and for every 6 ft × 8 ft panel we sell; a 6×6 at gates and corners. Gravel at the bottom of the hole, concrete to grade, and a day to cure before anything hangs on it.

Sold by the piece for pickup at our Bolton yard. Every panel page offers it as the matching post, so posts and panels load in one trip.

Questions about this lumber

Before you order.

Can lumber be delivered?

Loose lumber is pickup-only when ordering online. If your cart mixes panels and lumber, the whole order becomes pickup. For a lumber delivery, call 647-569-2163 for a quote, or order the panels separately for delivery.

Is there a volume price?

Not on this item; the per-piece price is the price at any quantity. For a full run, call 647-569-2163 for a bulk quote.

Is it kiln-dried and what is it rated for?

The 1×6 fence boards and 2×4 rails are premium, kiln-dried and above-ground rated. The 4×4 and 6×6 posts are ground-contact rated for in-ground use. Match the piece to its job: boards above ground, posts in it.

How do I pick it up?

Order and pay online, then collect at 240 Ellwood Drive West, Bolton, Ontario L7E 4W6, Monday to Friday, 9:00 to 5:00. Bring your order number and a truck or trailer; we stage the order and load with you.

Is a 10 ft post right for a 6 ft fence?

Yes. A 6 ft fence in southern Ontario sets its posts about 48 in. deep to get below frost, and 10 ft less 48 in. leaves 6 ft standing above grade, level with the top of a 6 ft panel or board. An 8 ft post set that deep stands 4 ft, so it is the post for a 4 ft fence. Use a 6×6 at gates and corners; the rest of the line takes 4×4s at 96 in. on centre.
