Trex 4 in. x 4 in. x 39 in. White Composite Post Sleeve

4 in. x 4 in. x 39 in. White Post Sleeve fits over a 4x4 pressure treated post. Post Sleeve Assembly tool is included and it is quick and easy to assemble. The free corrugated TrexExpress railing assembly tool is a cardboard "jig" that wraps around the post sleeve and shows the exact location to mount the brackets for the Transcends railing. No measuring is required and the brackets fit snugly into the cardboard to hold it in place while attaching to the post sleeves.
