Frequently Asked Questions
Up to 4 inches. Anything over that please get a bigger post.
We typically cut our pipe when building a jack post 3 inches smaller then the size of the post needed. This allows the Plate and Adjuster to fit snugly. Example: If you need a 75 inch post cut the pipe 72 inches.
