“I had about 5 of my neighbors just in awe of them when I was installing six of them yesterday. The hardest thing was to prep and level the ground before drilling them in. Honestly took less than 20 minutes. Went down very straight and easy even in very thick clay soil. One of the best products I have seen. 10 out of 10.”

| Fasteners | Recommended: (4) 1/4″ x 3″ hex head lag screws Sold Separately |
| Recommended Uses | Designed for footings for decks that are not attached to the ledger of a house. Keep deck ¾” to 1″ away from foundation or siding to allow for settling or seasonal vertical movement. Decks can be built as low as 2″ from underside of beam to grade and as high as 6′ from top of deck surface to grade. Posts should be braced to beams and joists for any deck 18″ or higher. |
Other | Be sure to check with local authorities for any height restrictions on free standing structures. See Engineering Reports for limitations of use. Prepare site by removing sod and laying down 3″ of ½” crushed stone and tamp down to compress. Crushed stone compresses well and is porous so water flows away from plate without eroding loose soil in heavy rain. Do not use for free standing posts such as fence posts. Not designed to provide significant resistance from lateral forces at top of post. |
Using a lightweight handheld ½” electric impact wrench and a 12mm six point socket, drive the auger deep into the soil.
Tighten the nut and compress the load plate against stop washer below the load plate.
Place the post saddle in the desired location. Tighten the upper nut to attach the saddle to the auger and load plate.

This guide provides users with solutions to common issues, enabling them to resolve problems independantly.
The Deck Foot Anchor™ does not heave up from the ground like a fence post that is literally popped out of the ground a little bit each year. The Deck Foot Anchor ™ remains anchored to the ground and moves with the soil as it expands up or settles down during freeze or thaw cycles.
The Deck Foot Anchor is not a frost footing and falls under Section R403.1.4.1. Exception 3(IRC)and Section 9.12.2.2.(7) (NBC). Therefore it is recommended for use with freestanding decks, unless the soil does not freeze in your area.
Terra-Shift refers to our unique friction release system in the bracket that protects critical post to beam connections on your deck in the event of any seasonal soil movement.
If any uneven uplift forces are imposed on your footings, posts will slide up or down independently as needed to protect and preserve the post and beam joints from separating.
Independent compression load testing has confirmed that each Deck Foot Anchor 4X4 saddle can support up to 15,000 lbs.
This is far more than your soil will ever support. So the Deck Foot Anchor is not the weakest link. Your soil bearing capacity is the limiting factor.
Watch this demonstration of how the patented Terra-Shift system works to relieve stresses that may build up during seasonal changes and threaten the integrity of your deck structure.
Regardless of the harshness of your climate, the post to beam connections supporting your structure will remain strong and sturdy.
Use the 24″ for most applications. Use the 36″ or 48″ auger when you want more wind uplift resistance or you are building on a slope. The auger length will make no difference how the Deck Foot will perform in frost as the above animation shows.
The deck will always be resting on the surface and will rise or descend marginally with the soil expansion and contraction. But it will always remain securely anchored to the ground.
GROUND LEVEL
You can build your deck with joists as low as 2″-3″ above grade if you wish. Simply hang the joists from the perimeter joist. If you want to extend the deck beyond the footing, extend the side perimeter joists 6″-10″ and fill with blocking joists along the length.
EASILY UP TO SIX FEET
With proper bracing in both directions from 6×6 posts to beams, you can make a six-foot high freestanding deck as solid as a rock. It’s possible to go even higher but it is not intended to support decks at a second-floor elevation.
Decks supported by concrete blocks that rest on the surface are susceptible to uplift in high winds and have to be secured to the ground with a webbing of cables and ground spikes.
The Titan Deck Foot Anchor™ holds your footings securely to the ground. Almost 2/3 of the United States and parts of Canada are in high wind zones.
For maximum uplift resistance, consider using the 36″ auger.
Pull out resistance (tension) from undisturbed soil varies by soil type and auger length. If you are building a project where known uplift data is required please see our Tension Test data for sandy or clay soils based on auger length. This is data taken from field testing by Intertek in a location in Colorado and is part of an extensive residential code compliance review program this is expected to be completed in the spring of 2022.
The Rule of Thumb is 6′-0″ apart for each footing. This corresponds to a design load of 50 psf and tributary areas over each footing of 36 sqft.
So the total load imposed on the soil below each footing would be a maximum of 1800 psf as the footing is just slightly larger than 1 sqft.
If you have a large deck where three or more beams are going to be used, consider adding one additional footing along the interior beam. This is because the tributary loads of any structure are always greatest in the middle.
Some soil is not well suited for augers. The soil may be full of rocks, roots or other obstructions.
The Deck Foot Anchor™ can be retracted easily enough and there is some latitude with where to choose to install each footing.
However, if you are unsure about your soil use a 24″ Bit Extender (or longer) with a 1″ spade bit and a cordless drill. Try driving the bit into the ground as deep as it will go. This will tell you right away if an auger will work in your soil.
Our 12mm high impact six point socket is designed to grip the hexagon drive head without stripping no matter the load.
This tiny investment can save headaches on the job site. If you use a low quality twelve point socket that does not fit as well, you are more likely to strip the drive head while under maximum load.
WARNING: Your experience with the Deck Foot Anchor is entirely dependent on your soil type. Rocks or roots or a weak impact wrench can prevent the auger from driving fully into the soil and an improperly sized socket can strip the driver head. Continuous torque for an extended period of time on the auger, once it has been stopped by a rock or immobile obstruction, can destroy the auger. The footing does not provide any significant lateral load resistance and should be used for compression load applications only.
This was a large multi-level deck that really shows off the usefulness of the Titan Deck Foot Anchor™. Three separate areas. All intricately designed to wrap around a hot tub spa and create intimate areas.
The first area was off the back patio door about 3-1/2′ high. The others were lower level platforms over a gradual grade sloping away from the house.
All 24 footings were installed before lunch hour.
Another building benefit is being able to use the Titan Deck Foot Anchor™ to easily drop beams within 2″ of the grade. Try doing this with a block…
You can also hang joists from beam face to beam face if you really wanted to hide all the beams of a low-level deck. That is next to impossible to do with blocks.
First, if we used concrete blocks we would have had trouble figuring out how to get the deck joist framing as low to the ground because they sit higher.
Second, the deck would just loosely sit on them. Here, each footing and post to beam connection is secured to the ground.
Third, we didn’t want to see cement blocks when you walked by the highest level deck.
WARNING: Your experience with the Deck Foot Anchor is entirely dependent on your soil type. Rocks or roots or a weak impact wrench can prevent the auger from driving fully into the soil and an improperly sized socket can strip the driver head.

WARMING: Allow wet posts to dry and acclimate to local humidity before cutting 2×4 rails to length. Larger (6×6) wet posts, in particular, can shrink up to ¼” and this can cause the connectors and/or the 2x4s to pull apart.

I used four deck foot anchors to anchor my wood pergola. It is most definitely not going anywhere! I was impressed with the quality of the parts. We did encounter some challenges with tree roots while putting in the anchors. That took a bit of tweaking and troubleshooting, but we were able to figure it out. Very happy with the product!
