Product Details

For 18-years, Post Protector has provided simple, slide-on barrier protection for in-ground posts. It works in conjunction with the chemical preservative as an important additional layer of protection against soil-dwelling and atmospheric decay fungi and insect infestation. Its first important to understand decay. Many believe that moisture CAUSES decay. Moisture is not the cause of decay but is 1 of 3 conditions needed for decay to occur. The conditions: 1 Moisture, 2 Oxygen and 3 Suitable temperature. These conditions enable the soil-dwelling or atmospheric decay fungi, as well as termites and other subterranean insects, to feed on the wood fiber. So the Decay/Degradation of ground-contact wood is not CAUSED by moisture but by the action of wood destroying organisms feeding on the wood. The chemical preservatives protection strategy is to poison the wood fiber, rendering it an unsuitable food source for the wood destroying organisms. The downside to that approach is that all chemical preservatives eventually lose resistance to decay and insect infestation. Post Protector becomes the perfect complement to the pressure treated (or cedar) post by simply providing a physical barrier isolating the post so the wood-destroying organisms have NO access to the post.

Q:Can the sleeve be installed on a non removable deck post? Because the post is supporting the deck I can not slip the sleeve over the top. Can the sleeve be split vertically and opened enough to go around the post?
by|Dec 1, 2022
1 Answer
Answer This Question

A:  Before I answer your question, let me clarify that this is not really a sleeve.  It is not open on both ends, only the top.  It is designed to be slipped over the bottom of the post before the post is placed in the hole to create a barrier between the wood post and the soil.  To answer your question, yes it could be cut open vertically.  But that would defeat the purpose of using it.  I believe there are other products that are wrapped around the post at the soil line that might be a better choice for your project.

    Q:does this come in true 4X4 or only nominal 4x4 (3 5/8 x 3 5/8)
    by|May 15, 2022
    1 Answer
    Answer This Question

    A:  I would say nominal. There is some wiggle room, but I doubt it would fit a full 4x4.

              They are easy to install. Just slip them over the bottom of the post and put the post in the ground. I did not screw them in figuring that if the post has a problem I should be able to work the post out without having to pull the post-protector out of the ground.

              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.

              The post was loose inside the post protector and rainwater could easily run down inside and rot the post. Maybe I didn’t read the directions carefully. Good idea but not sure it would do what it’s supposed to.

              Great way to extend the life of your post. Wish stores stocked this vs special order. It came quickly. Very happy and way to cut down if needed.

                  Poor all the way around
                  Poor customer service, arrived late when I talked to owner admitted didnt even have the product made. When arrived would have to still add the drainage holes before installing in a good design drilling these would be done in manufacturing process. They are a flimsy plastic cover that should your tiny 4 hold get plugged with dirt, debris or even a rock the post protector is going to hold the water like a bucket.
