Title: Easily installable protective sleeve for an embedded wooden post requiring uplift capability

Abstract: A sleeve for protecting from deterioration and anchoring an embedded end of a post in the ground. The sleeve, molded from unperforated, resilient material, conforms to the exterior post dimensions and extends for at least the desired embedment distance. One or more inwardly projecting notches are cut into the post. The sleeve includes one or more reversible snap domes molded into the sleeve at locations coinciding with the post notches. The snap domes flex to an outwardly concave position as the post is being inserted into the sleeve and then snap to an inwardly concave position once the post is fully installed and the snap domes align with the notches. The inward concavity of the snap domes extends into and engages the post notches to prevent the sleeve from being removed from the post. When embedded into the ground, backfill material prevents the snap dome from being deflected into the outward concavity position, thus anchoring both post and sleeve in the ground.
