The Xtractor is for removing hollow 4” and 5” vinyl posts set in the ground. It works on both posts with a concrete footer, and those without. It is done without harming the post above grade allowing the post to be reused. Simply drop in the Xtractor (attached to your own chain) down inside the post and pull. The Xtractor will remove the post and concrete without damaging the outside of the post. Now moving a vinyl fence is easy!
