Review: Well made and fits like a glove when using with 2-3/8 post. - My property is on a down hill slope so this helped get that extra inches to get the 9ft of privacy fence that I was going for. Extender has 3 holes pre drilled and comes with metal screws. I was able to weld to my pre existing post and the extender slides right in and fit like a glove.
Review: Fast shipping, exactly as advertised. Perfect fit - Worked perfect for my project. Guys forgot to get the longer corner and terminal posts so had no way of running Barbwire, this fixed the situation entirely without having to re-install posts.

### ⭐⭐⭐⭐⭐ Good Product
*by T***D on October 25, 2025*

The product was great exactly what I wanted the Amazon driver happened to catch me in the driveway and Hand delivered it. I did not notice at the time, but there was a tear in the bottom of the box and one of the post caps obviously fell out. Nothing to do with the product I’m sure it was just banged around in the truck or ruff handling somewhere.
