I have constructed many fences and gates before. I regret to say until recently I have never used an adjust-a-gate. Now that I have, I do t think I will ever build another gate without it. It is easy to use and makes a gate much sturdier than normal. Keeps it where your gate won’t sag after a few years.  The fact that it adjust to any size from 36” to 60” makes it usable on majority of gates. If you are about to build a fence, then be sure to use an adjust-a-gate to construct your gate. It is well worth it.
