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° - 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.

  • Simple slide-on installation
  • HDPE- material has 400 plus years of in-ground useful life
  • Light weight, flexible and strong
  • Attractive appearance-rich clay tone color with wood grain texture
  • Easily trims to desired height above grade
  • Integral uplift protection
  • Stronger, faster and less expensive than concrete pier and steel bracket method
  • Protects post from weed eaters
  • Net opening size is 3-3/4 in. x 3-3/4 in.
  • Includes (4 per post) 1/4 in. x 1-1/2 in. galvanized lags with EDPM bonded washers to attach Post Protector to post
  • Use attachment lags near grade level for ease of post removal/replacement

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?

Answer: 
yes they are sealed at the bottom. you can choose to put a filter bed at the bottom of the hole you dig and then put some drain holes in the post protector or just seal the top of the post protector like I did mine. they will prolong the life of the post.

Answer: 
The post protector is closed on the bottom, yes. We have a video in our digital assets portion of HomeDepot.com that explains the cause of rot and how Post Protectors stops/alleviates the problem. The speaker is a university expert on wood and lumber.
The video is also shown on the post protector Website.

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.

Answer: 
If you are placing your posts in concrete and have sandy soil, I would drill the drain holes at the bottom. I would use all of the lag bolts included and then go ahead and concrete them in. I did not use concrete and only used one lag bolt and my posts have some wiggle in them. I should have used at least two lag bolts. The wiggle is the posts moving inside the sleeves. One could probably add some shims Read More

Your situation seems to be conducive to natural drainage so I would just use the drain holes and not seal them up. Read Less

Answer: 
In short-The post protector creates a barrier between the soil and the post and without soil contact, decay doesn't occur.
No need to seal the top as water alone doesn't cause rot. We have a video on the site that explains decay in detail from a university expert.
There are pre-marked drain holes on the Post Protectors. You can drill those out per the directions and given you have sandy soil, that will

Answer: 
The Post Protectors are made slightly over sized as post sizes vary from moisture and manufacture. The Post Protectors are flexible and when you attach them they flex onto the post(This is better explained on the installation instructions). You can also shim if you have severely undersized posts and are concerned but this is usually the exception.
Hope this helps and if you need further clarification

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?

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 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 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 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 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 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 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.

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.
