    Really nice sleeve. Very thick vinyl and consistent color. Just loose enough to slip over PT 6X6.

    Very nice product

    Posted by Tom on Jun 9 2022

    We ordered these for 6x6 treated posts for our outdoor deck. They are really nice and much better than having to stain 6x6 posts every few years. The only issue we ran into was that they are very tight and some of our posts were slightly larger than the standard 6x6 measurements so we had to cut down the posts (and most of them were already installed). They look great and will be no maintenance.

    6X6 Vinyl Post Sleeves

    Posted by Mike S. on Dec 22 2020

    These sleeves fit perfectly over 6X6 treated wooden deck posts with approximately 1/8&quot; gap between wood and vinyl. This allowed me to run wiring for accent post lights from underneath deck up inside sleeves for a beautiful finished job.
