Description: Post Shield makes 4x4 wood post installation, replacement, and repair faster, safer, and simpler. Its design lets the wood breathe, lengthening post life, while protecting the post from standing water, weed eaters and mowers, insects in the dirt, and even chemicals in concrete and asphalt. With Post Shield, installation and replacement takes just minutes, with no "bracing" required to set a post plumbed and perfectly vertical. Post Shield is for use Every Where a 4x4 wood post goes in the ground. Though it is not structural (the post itself provides that function) it is designed for use with fences, deck footings, gates, retaining walls, planter boxes, mailboxes, and signs.

  • Fits a true 3 1/2- 3 9/16 in. square wood post
  • 28 in. Long, may be stacked for deeper applications
  • 4 Sleeves per pack
  • UV impregnated pvc construction
  • Green product and recyclable
  • Posts last longer, they breathe. Water drains and evaporates while concrete, dirt, and asphalt won't come in contact with the post, keeping those damaging chemicals away from the wood
  • Plumb posts in seconds. Just a level on the top before inserting the post and it will be perfectly plumbed and vertical. No more bracing a post while concrete dries or atanding on a ladder to trim post length
  • Gate center supports can be removed quickly for use with RV, boat, or trailer entry and exit
  • Mailboxes, raised flower beds, pet areas; all installed and replaced easily and safely
  • Color blends with nature, but is paint-able, if desired

Rated 4.4 out of 5 by 24 reviewers.
Rated 5.0 out of 5.0 by Nice for removable fence I wanted to build a section of removable fence so that if I ever needed to get something large in my back yard I could do so, these sleeves worked perfect!. I build 1 whole section of removable fence then built 2 gates in another area and used a sleeve to create a removable center post to eliminate gate sag. The post slide in and out of the sleeves easily, and are easy to install. If your going to remove the post for access you will want to cut them off flush and find a plug so debris don't fill your sleeve. Also be sure to use plenty of gravel under your sleeve for good drainage. July 6, 2014
Rated 5.0 out of 5.0 by 4x4 Protection These are great for being able to remove 4x4's easily. I used this for RV parking where I can have two secure gates that meet a 4x4 in the middle that can be removed when needed. The 4x4 slips in an out. Also, much easier to cement into the ground than the 4x4 itself. February 25, 2014
Rated 5.0 out of 5.0 by Good product works as advertised. it would be nice if it was a little less expensive April 14, 2015
Rated 5.0 out of 5.0 by Worth it After reading reviews I was worried these were gonna be too weak, but was glad to see they're made of thick plastic. They seem to hold the posts up very well. Getting them perfectly level is kind of a nightmare, but the pros definitely outweigh the cons. Will be using these again when I replace the rest of my fence. They fit treated 4x4's perfectly. Not sure about untreated wood. March 25, 2015
Rated 4.0 out of 5.0 by Good product, Great idea I bought these to put up two 4 x 4 clothes line posts that I want to be able to put away for the winter up here in Maine. I debated just using an appropriately sized piece of PVC pipe but came across these in my search for ideas. My only issues with them are that I wish they were a little thicker material and longer. The frost line up here goes pretty deep some years so I'm curious how that will play out in the coming spring. So far they are working great but haven't been removed/replaced after a winter. My advice using them is dig as small a diameter hole as possible that allows you to set the post if you have any sort of lateral load being applied and are not setting them in concrete. The lateral load I have is obviously clothes on the line. This is more physics than product related. I can see no issues with a straight up and down force other than if you have to replace a 4 x 4, what do you have to move or disassemble above them to allow you to get it out. August 4, 2013
Rated 1.0 out of 5.0 by Not what I expected I got these sleeves to use with a fence replacement with two large gates. The goal was to use the sleeves so that a removable 4"x4" post could be placed in the midpoint of the gateway to provide additional support when the 2-door gate was in the closed position. The first problem encountered was that the sleeve was too small for a standard 4"x4" cedar post. No big problem - I got out the belt sander and modified the post. While I was doing that, the sleeve that I was working with fell off the table and splintered! These things are way too brittle. Now I am thinking that I don't want to use them at all. I was planning on planting them in cement. If they self-distruct; I will be left with the problem of digging out the concrete support. Good idea, bad product. October 28, 2014
Rated 5.0 out of 5.0 by Simplify Post Repairs The posts were easy to install, and I have tested and found the posts easy to remove and reinsert. This should eliminate the need to break up the concrete should I have to replace a post in the future. August 26, 2014
Rated 5.0 out of 5.0 by Good Product Wood fence posts don't last as long as they use to. These sleeves make it easy to replace rotten posts without digging new holes. Slide the old post out and slide the new one in. They are easy to install and most likely prolong fence post service life. August 20, 2014
