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. x 42 in. and 60 in. lengths.

Post protector for 3 ply 2 X 6 Posts

Post protector also makes these for the 3 ply 2 X 6 laminate posts but I cannot find them on your site. Maybe I am looking in the wrong place

The protectors are not available on unfortunately. If you go to the Post Protector website I'm sure they can help you from there. Thank you for the interest.

do these post protectors meet code? In Pennsylvania we can't have post set in concrete, this would be set in plastic

Also, if you don't see exactly what you need on Home Depot's website, have a look at Post Protector's site and contact Post Protector's excellent customer service directly. They were able to work with me on a fast special order through Home Depot.

Rated 1 out of 5 by from Waste of plastic For the money, these aren't worth it. Water will easily seep its way into these protectors from above or below (as you put holes in the bottom), and WILL cause rot. I bought these before I found Perma columns, and returned them to Home Depot in order to have something that will actually last. Don't waste hundreds of dollars on this waste of plastic, they might slow rot down because direct soil contact can be avoided, but water still gets in. I would highly recommend Perma Column posts, or other systems that use concrete as a base, and keeps the wood where it belongs, above grade.

Rated 4 out of 5 by from As Advertised Just received my post protectors. I plan on constructing a post-frame building later this summer. I don't like the idea of putting wood in the ground and mounting the building on a concrete footing was too expensive/too much work. The post protector is a great idea. Install looks very straightforward. One of the protectors had a crack when it arrived. I called the manufacturer and they apologized and sent out a new one right away. Good customer service. Nice to work with a company right here is the USA.

Rated 5 out of 5 by from No reason not to purchase After tons of research I found this is the "Best product" to protect your poles. Also they are easy to install, light weight, great customer service if you have questions from the manufacturer, and made in the U.S.A. What more could you ask for?

Rated 5 out of 5 by from Great Product. Have used them for years. I’ve been building for better than twenty years and decay is commonly misunderstood. Many believe that moisture is the cause of decay when it is actually one of the conditions needed for decay to occur. Post decay occurs when the soil dwelling fungi use the wood fiber as their food source. That’s why the treatment in a pressure treated post is a pesticide not moisture protection. They basically poison the wood fiber so that the fungi won’t feed on it. The Post Protector is a barrier between the soil and the post. It’s another layer of protection working in conjunction with the treatment. It allows me to put the post in the ground with no soil contact. No soil contact means no decay. I’ve tried the $150, 150 lb. perma column once. Its purpose is the same as the Post Protector, to eliminate soil-to-post contact. At 150 lbs. and $150, it certainly is not easy to use or to pay for and definitely not DIY friendly. Having used Post Protector for years building pole barns and a couple of decks, I can say that it is the simple, affordable, effective way to protect in-ground posts, period

Rated 5 out of 5 by from Great product for protection of your posts! The product is a simple yet great design. This product will ensure that the posts will last a lifetime plus some. This was a product that will give you piece of mind when investing in a project that involves wood going into the ground.

Rated 5 out of 5 by from Great product I just built a 32x44 pole building and was not comfortable with treated wood being buried and in direct contact with ground. These gave me the peice of mind to bury and hopefully prevent rotting. Very easy to install and work with
