What type of blade do you recommend to cut these post sleeves?

What type of blade do you recommend to cut these post sleeves?
Asked by: Batman
I tried a test cut with the same combination blade that I used in my circular saw to cut the 4x4. It worked just fine, so I did all if the vinyl sleeve cutting with the same 7 1/4" saw. The blade was almost new, and I took it slow, cutting through one side and then flipping it over to finish. Easy-peasy. I had one cut that didn't match up perfectly, but a quick pass with the belt sander trued the edge right up.

I'm building a screened in porch, can this product be used over the 4x4s and can it be cut with a wood blade, what is the sleeve made of. thank you

Asked by: phil
I used it to cover new 4x4 treated porch posts and I cut it with a regular combination blade in my 7 1/4" circular saw. The sleeve seems to be made of the same stuff that white vinyl fences are made of - just thicker.

shiny or matte finish? Can they be drilled?

I want to use these to cover pressure treated 4x4s to support a garden arbor. Need to know if they are very shiny and fake looking, or more like a matte painted surface. Can I drill through the sides to attach lattice stringers? What happens if the treated wood inside starts to warp?
Asked by: omi
Shiny - much like a white vinyl fence post. Easy to drill through - it's plastic.. Your treated 4x4 post will likely dry very slowly and evenly because there's not a quick way for the moisture to get out. Fast drying is what causes warping. I didn't worry about it.

4 in. x 4 in. x 108 in. Composite Post Sleeve is rated 4.0 out of 5 by 8.
Rated 1 out of 5 by from Shipped damaged post Home depot shipped a damaged post as product could not have been damaged in shipping . Plastic had been folded on edge. Plastic can't be folded without breaking .

Rated 2 out of 5 by from Disappointed We needed 8 foot post sleeves for our deck. We purchased Veranda railings (made by Fiberon). Veranda did not have tall post sleeves. Fiberon did but they were ridiculously expensive. Found these at about 1/2 the price and were made out of a decent material. The problem was with shipping which basically scratched the heck out of the sleeves. We needed 5 of them. Out of the first five we received, 3 were "good enough" and the other two were severely scratched. They were only wrapped in plastic like saran wrap which was not enough protection. Returned and re-ordered two of them. They arrived scratched also but were able to use them with the bad sides kind of hidden. Shouldn't have to play this kind of game for a $45 piece of plastic! If you order these, order twice as many as you need and be prepared to return half of them.

Rated 5 out of 5 by from Solved my rotting wood problem. We had 3 turned pine posts on our porch. As we live in Florida, the bottoms of them were rotting - wood has an awful time here. Obviously, we need treated wood posts, but they're ugly and hard to paint. Slip one of these over your treated post with a couple of plastic end trim pieces and your ugly post problem is solved! I was able to re-use the existing post mounts by slipping the cover over the bottom one and cutting two slots in the top cover to allow the flat parts of the top mount to slip through. Once in place, we put screws through the vinyl, the metal and iinto the wood, slipping up (or down) the end trim to cover the screws. A little caulk to fill the slots that we cut, and to keep water out, and we were done. They weren't that cheap, but the finished look is worth it. I didn't really want another turned pine post on my porch....

Rated 5 out of 5 by from Works perfectly Needed a longer length to cover 4x 4 for a birdhouse. Worked just as I had hoped and better than painting staining pressure treated wood.

Rated 4 out of 5 by from Cross over post sleeve review Posts worked great and matched up nicely with all standard trim and cap pieces. Was able to get 3 - 36" post covers out of each length.

Rated 5 out of 5 by from Good to dress up and to avoid painting a 4 x 4 post. 4x4 fit inside the post sleeve with room to spare. I had rounded the corners of the post but don't think that is necessary. Post sleeve was well wrapped for shipping. Suggest picking it up at the store.
