Are these really adjustable? Fit a 4 1/2 inch by 4 1/2 inch posts!

Asked by: Gma5
By "adjustable" they are referring to the base being able to slide a little though a slot on the bottom.

Can u use this to support a fence post?

Asked by: Mikey
The Strong-Tie installation guide says the adjustable post base should not be used for fences: "Post bases do not provide adequate resistance to prevent members from rotating about the base and therefore are not recommended for non top-supported installations (such as fences or unbraced carports)."

I set 4x4 posts on the bases at the end of stair rails. They do excellent job keeping the post ends out of water. I used bases on the posts on my studio porch several years ago and they are still doing a good job keeping the posts out of water. Easy to apply with galvanized screws (into wood).

A curious item to review as what really matters is if it is still strong in a few years. Installing went ok except the expansion bolt we used would not grab the concrete, but because the post base also had holes for screws we were able to attach it so.

I replaced an outdoor stair hand-rail and needed a mount to the concrete retaining wall. I wanted to use Cedar and these were perfect for the job. This hand rail will be around a long time.
