Tisan Post Anchors are an easy to conceal wood post surface mounting and anchoring system. Made from high strength aluminum. Use with deck post for the anchor. Use it for gazebos, pergolas, deck railings, support posts, patio railings, or anywhere you need a clean looking, strong, wood post connection to any surface - wood, composite or concrete. A great solution to installing composite post sleeves. Most post skirts fit over the Tisan anchor with little or no modifications.

We recommend using these Cedar Post Skirts to easily fit over Tisan post anchors and keep a consistent cedar look throughout your posts.

Tisan post connectors are the recommended option from the deck installation experts at The Deck Store.

    Exactly what I needed. Very strong.

  2. Good product review by Phil on 9/16/2020
    Overall Product Rating

    The post anchors are the best option for surface mounting 4x4. Strong, stable, makes an excellent base for a railing system. The only issue is that the base covers which came with the composite post sleeves do not fit. This is because of the 2 piece design of the covers. Most one piece covers should fit over the achor and conceal it. Posts are very rigid and should hold up to a lot of use.

  3. Tisan 4x4 Post Anchor review by Philip on 7/3/2020
    Overall Product Rating

    The anchor allows one to attach a 4x4 deck post to the surface of a deck. I ordered with hardware and glad I did as the bolts are sized right and great quality. You need at least 3" of solid wood under the Tisan plate for a solid mount. And it is really solid with no deflection. I like it a lot and it is indispensable in some situations.

    Don't waste your time with other post anchors, seriously, we've tried so many and these Tisans are the Best!

  5. Superb! review by Victoria on 6/19/2020
    Overall Product Rating

    Of all of the post anchors we've used over the years, these are clearly the most secure. One word of advice, they do need a firm "box" built underneath the deck in which to secure them. (as most anchors do). To simplify your install, make the boxes you build under the deck a few inches or more larger on all sides as no one will ever see them and it gives you a little more play as to where you can put the post in case you need adjustments to be made. We love the Deck Store Online!

  6. Exactly what I needed! review by Greg on 6/14/2020

    I have very high outdoor decks with log railing that I am replacing. These Tisan Aluminum Post Anchors are perfect for securing the 6 inch round vertical posts. . . exactly what I needed.

  7. Quick and easy review by Nathan on 5/17/2020
    Overall Product Rating

    I ordered 10 of these and they worked out wonderfully. It took me longer to set up and cut the posts than I’d did to install them onto the post bottom. It would be nice to have either another small screw hole similar to the center screw to keep the base from moving while setting the lag screws or have a recessed post area. Still, the product is solid and beats blocking the posts the “standard” way. This product earns a repeat purchase in the future!!

  10. A miracle! review by Ray on 4/29/2020
    Overall Product Rating

    I had been designing my deck railing for about a year and wanted to do it just right. I didn't want it to look thrown-together. I desired a professional look. Right before I purchased all of my materials, I stumbled across the Tisan post anchors and was excited to see such a simple design, yet durable!

    I purchased these right away and did not have to wait long. They were delivered in 3 days and in just the time I needed. There were only 2 anchors that lacked the starting hole fully drilled through, but that was non-issue whatsoever!

    Don't hesitate to buy this product! You will be extremely satisfied with the look of your railing/project and durability!

  11. Easy to install. Pretty sturdy. review by David on 4/21/2020
    Overall Product Rating

    Anchors were received quickly after the order. They’re not the least expensive thing l could’ve used but the ease of installation offsets the cost. Sturdier than less costly products I’ve tried adds more value. Couldn’t be any more straightforward to install. Easy to shim on uneven concrete, the right anchor for my project.

  12. Exactly what was needed review by Daren on 4/7/2020
    Overall Product Rating

    I found these anchors when I was searching for a solution to a remodel of a 1950s lanai. The posts that hold up the lanai roof angle out from top to bottom and I wanted to keep that look but I needed to get rid of the 2x4 footer they were originally mounted on. These fit the bill. I mounted them on the 20 degree angle bottom of the posts and then used tapcons to secure them to the terazzo floor. They worked great and they look good to. My father in law is an architect and I've been consulting with him. When he saw these he thought they "look sturdy". They are. I did have one or two that had rough machining marks on the edges. This is not important for me because I will tile right up to the plates but others may want a nice clean look on the edge.

  13. Love these! review by Kelly on 3/18/2020

    I have a deck with no railing but I also don’t have much construction experience. These anchors are AMAZING. They have a small footprint and once in place the posts won’t budge. They’re worth the investment!

    Product was extremely stable fastened to a paver porch with tap cons. One plate was not drilled all the way through but easy to fix

  17. Good idea, poor quality control review by Sean on 9/17/2019
    Overall Product Rating

    The anchor is a functional piece, but quality is very poor in manufacturing. Very rough exterior edges, sharp edges and burrs all over part, and the thru holes are significantly off center. We are talking 1/8" off center here. I had to grind down the head of my screws to make them fit in correctly. For $22 a piece I am quite disappointed with the quality when we are talking about the simplicity of this part.

  21. Real good review by Robert on 8/7/2019
    Overall Product Rating

    Everything looks good and will make my installation simple. The person counting the screws should be more careful as I am short one of the long screws and have one extra of the short screws. In my situation it will not be a problem but one extra of each size might be a good policy.

  22. Super product review by Stanly on 8/6/2019
    Overall Product Rating

    Was wondering how I was going to mount the wooden 4x4 post to my deck. The answer was this product.. Amazing how easy it was.. After screwing it to the deck I really pulled hard on the post and it did not move any.
    Delivery was fast also..
    Thanks for a good product..

  23. Good Material, Holes a little dicey review by ROBERT on 5/24/2019
    Overall Product Rating

    This is a quality bracket, the only issue was I had to bore out some of the holes they were irregular when it arrived, so screws would not fit through some of them.

    Great stuff. I painted mine black when I first got that worn aluminum primer then paint. It's been a couple of years and they actually still look like they were manufactured black. No movement, no problems, came back to order more.

  30. Just What I Needed review by Michael on 7/29/2018
    Overall Product Rating

    I stripped my deck down to the frame for a complete makeover, only to realize after I had reinstalled composite decking boards that I needed to add a couple of posts for handrails. I went to Lowes and picked up a couple of the cheap and flimsy brackets that they sell, got home and decided that they weren't going to get the job done. So, I looked on The Deck Store's site and saw these, the Tisan aluminum anchors. Checked out the installation videos, decided that they were what I needed and placed an order. They came quickly, I added some blocking under the deck to ensure they had something to lag on to, put them up and they are rock solid. It's great to find what you need and have it work so well.
