No External Bracket, No Exposed Hardware
Most post bases attach to the outside of the timber, but not the Easy Tie. The hot dip galvanized knife plate connects inside your 6x6 post, keeping all hardware beneath the post and hidden from view. At ground level, all you will see is timber sitting on a low-profile galvanized base - no bracket, no bolts, and nothing competing with the structure above.
Just Right for Smaller Frames
Perfect for pergolas, deck posts, smaller timber structures, or even fence posts! But if you're building something heavier - your dream timber frame home, weather-proof event pavilion, or any structure requiring maximum uplift and compression resistance - the best of the best is the 8x8 Post Base Anchor Kit for Concrete.
How It Goes Together
Get ready to enjoy the easiest concealed connector system. First. the knife plate anchors to your concrete slab with traditional wedge anchors and the standoff slides over the top. Then, cut a slot in the bottom of your timber post. Next, set the post down over the knife plate and drive the two self-drilling dowels straight through one face of the post.
No need for perfect layout or drilling - the dowel screws drill thru the knife plate for you and provide the shear strength needed, all in one step. What's more, they're the perfect length to prevent drilling through to the other side. Afterward, you can plug the holes for complete concealment.
What You'll Need
- Circular saw, chainsaw, or other method of cutting the slot in the post bottom
- 3/8 in. concrete anchors — wedge anchors or Titen concrete screws
- Hammer drill and 3/8 in. concrete drill bit to anchor the base plate to the slab
- High torque drill or impact driver for the self-drilling dowels into the post
- Wood plugs/dowel rod (optional, for a finished appearance)
Raised Off the Concrete
The post base standoff keeps the post bottom 1 inch above the concrete, eliminating any end grain contact. Most importantly, removing direct moisture contact will protect your structure from long-term deterioration. This simple detail meanningfully extends the life of your building.
Built for Exterior Use
The entire kit is hot-dip galvanized steel - engineered for an exterior, high-humidity environment. The galvanized finish handles the conditions that do the most damage at ground level: standing moisture, soil contact, and seasonal weather cycles. The self-drilling dowels are zinc-plated.
