Will this work on a 4x4 fence post with vinyl over it?

AnswerThere is a "lip" at the top of the piece so if it's a tight fit that slides on all 4 sides, probably not. If it's a vinyl mailbox then possibly

Does it matter which side of the post you put it on
Asked by James June 6, 20185
AnswersIf it's a mailbox, it doesn't matter what side you mount it on. If you have a fence attached, there's only one way of course.

Would this work for a vinyl fence post?
Asked by Jesse808 December 4, 20174
AnswersI do not think so. It requires putting screws into the wood to hold it up right.
Will this work if my post is rotted 8" up from the bottom? My post is measuring at 4x4 inches, will it fit around it?

I first learned of The Post Doctor after watching several DIY videos on YouTube, and selected this product because it seemed easy to install. The Post Doctor worked perfectly and allowed me, a 57-year-old woman, to repair the fence by myself AND for minimal cost. I painted the metal to blend in with the fence, and I am very pleased with the results!

Don't Buy This Product
I bought this product and when I received it I found out that it is not designed for anything other than a vertical post. If there are horizontal braces which hold the boards - which almost all fences have - it cannot be used. They said I could return the product and get a refund but after several attempts - no refund.

Quick and Very Sturdy fence post repair
I repaired eight posts in my backyard including a ten foot tall section. One went on the gate support post that was leaning so bad that the door had to be lifted to open prior to using the Post Doctor. The units worked great. I've dug the cement out of the ground before, and this was a life saver.
