Good enough but scratches very easily

Would Not Recommend

I bought a single post sleeve to cover a 4x4 installed for a retractable hose reel. This one worked perfectly and seems like it will last awhile in our temperate climate. The only thing I dislike is how easily the composite stretches. My fingernail left scratches on it!! This isn’t a dealbreaker for my single post but I would not be happy with the durability at all if I used it on an entire deck and would find an alternative brand/material.

Quick way to encase your deck rail posts.

Would Recommend

I have found these to be a quick way to upgrade my deck to the trex system. Was able to strip my deck back to the underlying framing and posts, then upgrade with trex. No more peeling paint.

Customer service leaves a lot to be desired.

Would Recommend

Purchased 10 Trex post sleeves online Also purchased railing, post caps, posts and base trim, 2300.00+. Paid 79.95 shipping. Order is coming from 3 different locations and n store pickup. That makes no sense, first delivery came this morning. One sleeve was broken after I unboxed all of them to checked for damage. Took it to my local Lowes and they refunded the cost. This is where the service is bad. Service counter staff said I can order online again but would cost 79.95 shipping or drive to ot...

Great looking deck railing

Would Recommend

We really like this product line for deck railings. One important note for DIY installation: you need a rather large saw to cut this product. Do a couple test cuts first before cutting it to length. We found that our 12in miter saw did not have enough clearance to cut it and we have to be extraordinal careful to not mare the outer coating.
