OZCO 20550 OZ-Fence Post Extender, (1 per Pack)

OZ-Fence Post Extenders allow the height of your fence to be increased by up to three additional feet in just a couple of minutes. Just insert the expanding assembly into your post, tighten the nut to make sure it fits, and twist the extender on the bolt until it’s secured. No digging, no ripping out the existing fence posts, no need to spend a fortune on a brand new fence. The only thing you’d need is a 3/4-inch wrench and 5 minutes of your time. The extender can make your fence up to three feet taller, but if you wish to add just a couple of inches, you can always cut it to a shorter length.
