We needed to replace brackets on post that blew down in a severe windstorm. Ordered 3 of these and I am very pleased. They are very sturdy and the rebar type prongs that go in the concrete are strong as well. I appreciate they had both true 4 x 4 and 3.5 as 4 x 4 size.

These are nice and heavy duty but they’re about 3/8” wider than the 4x4 posts I used so watch out for that. Had to make shims to fill in the gaps. I also used them to install a fence/ gate on an existing sidewalk so I cut the legs off just above where the legs were welded together and drove them into 4 matching holes I drilled in the sidewalk. I put some epoxy in the holes to make sure they stay put. Very solid! Made a very stable fence/gate.

They didn’t work for my application but they are nice and heavy and I would purchase them again should I need them anchored in the slab.

This post holder is rock solid. A 6' x 6" x 8' tall timber post is held solidly without additional bracing. This is an excellent product.
