Product Overview

Post Protector is a slide-on barrier system protecting in-ground posts from decay by eliminating soil-to-wood or concrete-to-wood contact. Decay occurs when the following conditions exist: Moisture saturation of wood fiber, Oxygen, Temperature 40° to 100°F. These conditions enable the soil dwelling micro-organisms, to colonize the post using the wood fiber as their food source. This consumption of the wood fiber is otherwise known as decay or rot. Post Protector allows for typical post-in-ground foundations without the decay causing micro-organisms ever having access to the post. The treatment in a pressure treated post is a pesticide used in an effort to make the wood fiber an undesirable food source for these micro-organisms. The treatment is effective initially but loses its effectiveness as the chemical migrates or leaches from the post over time. Post Protector eliminates this chemical migration and keeps the treatment with the post where it belongs. Common applications are decks, pergolas, fences, pole barns or any post-in-the-ground project. Available in 4 in. x 4 in., 4 in. x 6 in. and 6 in. x 6 in., 42 in. and 60 in. lengths.

Customer Questions & Answers

What experience do you have with these?

I have CCA treated 4"x4" fence posts in concrete that have failed after 17 years. I have no idea how long the "new" treated posts will last. Is there any evidence these sleeves will help my new ACQ, CA-B or CA-C treated fence posts to last that long? What I've read implies the sleeves are closed on the bottom. Is that true?
Asked by: Hucfinn
Yes, they are closed on the bottom but on 'outdoor' post applications, you drill out optional drainage holes located on the base uplift rib for drainage. A typical outdoor post installation goes as follows: slide Post Protector over the post, affix the PP to the post with provided hardware according to installation instructions, drill out option drainage holes on base uplift rib, set post on solid concrete footer or 4"-6" crushed stone footer, initial back-fill material 4"-6" stone for drainage, balance of back-fill material can be concrete, soil, or stone, make sure that the top edge of the PP is 4"-6" above grade, PP are weed-wacker proof too. Any rain/snow running through the PP and draining has NO ill effect on the post. MOISTURE is NOT the cause of decay, but one of the conditions needed for decay to occur (Conditions for Decay: moisture saturation of wood fiber, oxygen, suitable temperature, 40-100 degrees). When these conditions exist, soil-dwelling or, as in Hucfinn's case with concrete back-fill, atmospheric micro-organisms will colonize with wood post, using the wood fiber as their food source, otherwise known as DECAY. PP retains the speed, affordability, and strength of direct-burial post foundations and acts as an additional layer of protection to work in conjunction with the chemical preservative. A physical 'barrier' so micro-organisms don't have access to the post.

Any reason these couldn't be set in concrete?

Want to do cedar 4X4 garden fence but have sandy soil and need more strength on corner posts. If set in concrete, would you seal top edge with silicon? Leave bottom holes open and below concrete level or could I completely seal these top and bottom.
Asked by: GardenD
On an 'outdoor' post application (any post that will be exposed to rain / snow - deck, fence, etc.), slide the Post Protector over the post, affix PP to post with provided hardware, drill out option drainage holes on the base uplift rib, set post on solid concrete footer or 4"-6" stone footer, initial back-fill material should be 4"-6" stone, balance of back-fill can be soil, stone, or concrete!

If the post opening is 3.75 in. and the post is 3.5 x 3.5,, am concerned/confused about the excess space when the post is inserted. Do I shim or...?

Asked by: LJ
No need to shim. The Post Protector will slide easily over you 3.5" x 3.5" post and the fit is perfect!

how easy is it to remove a post from the protector?

I want to use the post protector to put a post in the ground for a gate and then remove the post and put it back in. This may happen frequently during camping season. Was thinking of putting it in concrete with rocks in bottom of hole for draining. Would the post protector allow that to happen? What damage to the post and protector might occur?
Asked by: Wade
Yes, you can use them to create a 'removable' post. Here is a removable 4x4 post placed in a Post Protector with drainage holes drilled open, 6" stone base/footer, 6" stone as initial back-fill, and soil as balance of back-fill. https://www.youtube.com/watch?v=82_KFB9E1NA

4 in. x 4 in. x 3-1/2 ft. Cedar Tone HDPE Composite Fence Post Cover is rated 4.8 out of 5 by 8.
Rated 5 out of 5 by from don't put wood posts in the ground without these I build a lot of pole barns. The weak point of any pole barn is the wood in the ground. Doesn't matter if the wood is treated or not, eventually it rots. I used to pour concrete around the posts, but if any moisture gets between the concrete and the post, it can rot even faster. The post can shrink allowing moisture in the gap between the wood and the concrete. Post Protectors eliminate ALL contact with the soil. Also, there are molded ridges in the product for uplift protection. No more drilling through the posts to insert rebar. I like that there is a protector for just about any square pole. Unfortunately Home Depot doesn't yet carry all of the ones available. If you use laminated poles, they're available. I like to buy from Home Depot for the free delivery when I can. If you want lumber to last, whether you are building a fence or a pole building, start with these.

Rated 5 out of 5 by from Don't build a pole building without them I use these all the time anymore as a builder of custom barns. Even with pressure treated lumber, rot is inevitable. This virtually eliminates it. I just wish Home Depot carried these protectors in other sizes. Fortunately, other sizes are available direct from the manufacturer.

Rated 5 out of 5 by from Great product! I have used this product before for my mailbox post and decided to use it for the bird feeder pole because of the ease of replacing a damaged pole and the extended life it offers to the post. This post protector has a bottom with holes along the vertical edge so water drains out. Without a bottom the wood post would have a shortened life. This product also has rippled edges so water can drain more easily down the sides of the pole and out the drain holes.

Rated 5 out of 5 by from Great Product and Excellent Service I've used these post protectors before building a fence around our organic garden. Didn't want the pressure treated wood to leach into the garden. I also sealed around the tops with 100% silicone. I did have a problem with the order, wrong size sent. I called Home Depot customer service and they got Ken from Post Protectors on to correct. Everyone was very helpful and took care of the mistake right away. This is why I gave them such a good review. Anyone can make a mistake but it's how you handle it that makes a difference. They did just that, Thanks Everyone.

Rated 4 out of 5 by from Easy to install I won't know how I feel about the product for about 10 years, which is why I gave this a "good" rating and wasn't sure about recommending it--recommendation is based on installation and promise of success. Easy to install--the holes have to be deep, which was a bit tricky, since a post-hole digger must splay out at the top to pick up soil. Other than that, all went well. I did not use the screws as I want to be able to remove the posts. I did notice on some (I bought 4) that the thickness of the plastic was uneven: thicker at one end and thinner at another of the same side. No biggie, but might speak to a later quality issue. I am a (handy) woman in her 60s, and if I can install them easily, so can almost anybody.

Rated 4 out of 5 by from Fit the Bill I needed something to protect wood posts that where going into the ground next to a lake. So, the underground parts would be in and out of water as the lake rises and falls over the year. These sleeves will be perfect for keeping the water off of the posts. They were easy to use and I anticipate they will protect my posts for many years.

Rated 5 out of 5 by from works great I would recommend this to anyone that will be installing post in the ground. they are simple to install and add extra life to the post. I sealed the top of the post protector to prevent rain water from getting into it. mine are installed out in the open so I felt it was needed.

Rated 5 out of 5 by from Best solution !! Great product......Can be used in any post/fence application for guaranteed DRY posts. Post Protector sleeves and isolated the post from any moisture, chemicals in soil or any seasonal natural run-off.....Making the wooden post completely isolated and dry.............extending the life of the post exponentially in the process. No doubt, I would recommend Post Protector to anyone.
