Product Details

For 18-years, Post Protector has provided simple, slide-on barrier protection for in-ground posts. Remove the ground contact and extend post life. Post Protectors are a chemical free solution to improved post life, designed to eliminate ground contact where micro-organisms in the soil feed on wood fiber. The 4430 doesn't require hardware or fasteners and therefore doesn't offer the same uplift protection like our other models but is perfect for fences and other shallow embedment applications where post holes are dug at around 2 ft. The 4430 can be used for embedments greater than 2 ft. as well. The 4430 separates the first 2 ft. of the post from the soil which is the most critical part of the post. The soil below 18 in. does not contain enough oxygen for wood-eating microbes to thrive and cause rot and decay. The 4430 takes advantage of this fact as a price-leader in the Post Protector product line.

    Answer This Question

    A:  I would say just a little larger, you can slip a pressure treated 4x4 into the sleeve easily. I had to replace a 4x4 recently, just pulled the bad one out and slipped the new back in, no problem..

    by|Jul 11, 2022

      A:  I have purchased the 4x4x30 Post Protectors and installed them over a 3-1/2"x3-1/2" wooden post and then inserted them in the ground and finished with concrete around them. I checked today, 07-10-22, and the inside measurement is 3-1/2"x3-1/2".

          Q:Are these made so you can replace the posts in the future without having to re-dig a new post hole?

          Answer This Question

          A:  The usefulness of a sleeve for replacement is not the intention but is true. A post 2 feet or more down has never required concrete to be rock stable and IMO/experience, dirt fill is 100% better. A gate post could warp due to the weight too.

          by|May 21, 2022

            A:  Yes, you can remove your post and slip a new one if needed. I let my sleeves extend 6" above ground to help keep the dirt out and also better protection. Thanks Don L

                Wish that it is a little tighter so that the fence post does not wiggle as much after inserting and putting in down in the ground with cement. Thanks

                It came a bit crushed and I had to bend it a lot to get it to fit on the post. Once I got it on the post it worked as expected.

                Post Protector 4x4x30
                Came little distorted, but we were able to fit it on 4x4 P.T. post and install all in the ground. It's only few days in the ground, but looks like should last for a long time and mainly, we should be able to replace/repair pressure treated post in the future without digging.

                Used to create removable posts
                I used this to create a sleeve inside a poured concrete pad, so I could remove 4x4 fence posts that I don't use all year. I put the posts the sleeve, poured 24" deep concrete around it, then let it dry. Now I can remove the posts at end of gardening season by sliding them out. Works great for this purpose.
