Product Overview

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

Customer Questions & Answers

Is it sealed on the bottom as well?

Asked by: tucsonguyt
No - it is supposed to wick up moisture. You use stone at the bottom to help with moisture flow (up and down). There are ridges internal to allow for air/moisture flow.

Frost line is 42", how can I use these if they are only 28" long?

Asked by: Tom
Use scrap material, metal or pvc, as mending plates on the outside of the sleeve. Drill and fasten with small pop rivets, joining the two sleeves. Worked great, very sturdy, enough clearance inside that the post slides past the rivets.

are these strong enough to use for adding an extention to an exsisting post?

Asked by: und
Really not sure what you are getting at here--do you want to stack one 4 x 4 on top of the other, end to end? If yes, I would suggest doing what I did to extend the height of my gate posts: cut 4 lengths of 2 x 4, bevel all 4 edges to give a pedestal appearance, then screw the 2 x 4 into the bottom post, then the extension. A 1 in. thickness would be sufficient if you can rip a 2 x 4 width-wise. I strongly discourage using these for that application because the fit is not snug unless you use a true 4 x 4 for both ends. If you have that situation, you could use this in the same way as described above, screwing it into both ends. But--this postshield is pug ugly. I don't know where they get the color from. It should be brown brown, not orange brown. Maybe it's a function of the extrusion process.

I want to put a birdhouse on a post at least 8 feet tall. How long and deep in the ground?

Asked by: Benny
I would buy a 10 ft. redwood post, set the postshield 24" into the ground with 6" of rock underneath (dig a 30" hole). Use a form tube, at least for the top 8", of about 10" diameter. You'll need 2-3 bags of 50 lb. concrete mix. If you dig a nice round hole you can skip the form tube. It's kind of overkill for just a birdhouse, but you will need that depth of concrete. If you have clay soil, you should err on the side of overkill because the weight of the mass, if a 10-12" diameter, will keep the concrete, and thus the post, from shifting when the clay gets wet or dries out.

4 in. x 4 in. x 28 in. Protective Sleeve for 4 in. Square Wood Posts (4-Pack) is rated 4.0 out of 5 by 44.
Rated 2 out of 5 by from 4 stars if not bent... I bought a couple orders prior to this review, and had an overall good view of this product. The only downside at the time being was the price point (at 10 bucks per unit, the cost seems pretty excessive) and the fact that I had to wait for shipping (it took about 10 days for the first order). Otherwise, the product was as described and worked how I imagined. I recommended it to a few people in fact. I'd give it, at that time, a 4 star rating. (If the price was better, 5 stars) The second time I order a few more- chalking up the cash for an item that I had now put some trust into. Unfortunately, after waiting for them to arrive, the units where not square in shape. They were warped in such bad condition that you could not possibly put anything close to a 4x4 into the sleeve. The material is thick enough that you can not bend it back into the proper shape, so that tells me that they left the warehouse/store that way, which is very poor service in my opinion. It's also frustrating to think I may have to wait many weeks to get a proper order back, by which time I was hoping to have my project complete. I have not yet returned the item, because of the great inconvenience, but will have to go through that process, so for the time being, I have to give the product 2 stars. If this had been my only order, I would give it 1 star, but the prior order tells me that the product, when sent in proper condition, is good.

Repairing 7 4x4 posts broken off in a windstorm by jackhammering the footings loose and sliding PostShields deep around the stumps before pouring new footings on top. The shields have worked very well indeed. My posts are actual 4x4s

I used this "post sleeve" for my Mail Box post ,so now if a snow plow truck snaps it off I should have an easier time replacing the mail box post. I only wish that I was able to buy only one sleeve not a package of four.I had to shim mail box post about 3/8 " in sleeve because post was not the exact same size of a 4 X 4 . Over all I was very happy with end results.

Had to do a little planning to insert the timber with some assurance that I could remove the post later since I was installing removable fence panels.

Rated 4 out of 5 by from A little tight Good product, but a little too tight on some 4x4s. Had to pile drive a couple on concrete sidewalk to work them on. Would also be nice if they were about 4 to 6 inches longer.

Rated 1 out of 5 by from Not what I wanted Product works as a sleeve over the 4x4, and fits well with no problem, but I wanted a sleeve with and enclosed bottom. Beware if you are looking for a "post protector" brand enclosed bottom sleeve, this is not it.

Rated 1 out of 5 by from They are unsightly and a waste of money! My neighbor- Bless her heart had to have them after this being the 3rd fence we have replaced between us in 20 years. We had to use silicon to fill the gaps. They cracked where we used a rot board on the bottom of the fence- they are plastic. They are not made to keep a fence from rot they are made to be able to put another post in when it does rot. They fill with water...now why would I want to tear my fence part in another 7 years and replace it. I did my research and actually found a product that works which we bought and used on the other side. Seals the post completely to prevent rot,but I will not mention it here out of respect. Waste of money, very ugly and they are not all the same exact dimension. Can not nail into them without completely cracking them. We are going to remove the Sleeves and try and salvage our fence. My advise is do not waste your money, worse you will not be happy and stare at them for however many years they last wishing you would have just sloped the concrete away from the post. Im 66 years old and am that unhappy to take the time to write this review, I dont even like to write deposit slips at the bank. I like The Home Depot too, but those other reviews I just read, are from the people that make them! The only thing they would be good for is the guy who said he made a removable section, but it will wobble.

Rated 1 out of 5 by from Good quality for a useless plastic sleeve Sturdy construction, but EXTERNAL measurement is 4" x 4" which means the interior size is too small to fit a standard 4x4 post inside without shaving down the post. (Which is a major pain for the bottom 28 inches of each post.) These are heading to the trash can instead of the ground.
