Adjustable and durable, the Tree-Mate-O provides protective, flexible support, allowing a newly planted tree to gently sway while improving the form, taper, and root strength of the tree. To use, simply drive a "T" or "U" post into the ground 10" from the tree, remove the 3" snap-out section of the Tree-Mate-O and secure it to the post, position the tree in the ring, replace the snap-out section, wrap the EPDM band around the tree below the Tree-Mate-O ring, and hook band ends up, over the side tabs of the Tree-Mate-O. The Tree-Mate-O can be used with all types of trees and other similar tall plants plus it is reusable. Fits both green "T" type fence and light duty "U" posts. Comes with one EPDM rubber band. Made in the USA.
