Zlinke 6 PCS Metal 4×4 Post Base,Inner Size 3.5"x3.5" Post Base Brackets Heavy Duty Powder-Coated Post Anchor Matte Black Wood Post Brackets (Black 6pcs)

Great product with a modern look. Very sturdy and my 4x4’s fit tight in the 3.5” opening. Definitely would buy these again, quality for a good price.

Made our porch job easy. Very sturdy.

Post flange, worked perfect to build a bar top on deck

I know these are meant for vertical posts, but I'm using them as post brackets for my deck railing. I have fourteen 4x4 cedar posts that I'm going to use for my deck railing. I was looking for post brackets and ordered these. They are nice looking and appear very solid. I was somewhat disappointed that most of my posts don't fit in the bracket. I had to use an angle grinder, sander and wood file to adapt the posts to fit (see video). This created a lot more work for me when I thought I was almost done with my project. The inside diameter of these is 3.5 inches...the same size as 4x4 posts, so they won't fit in without alteration. I've seen other brackets meant for 4x4 posts with the inner diameter of 3.7 inches which would have been the ideal size so the posts fit in as-is (I didn't like the way they looked, so didn't order them) Other than that, I am pleased so far. I've seen some other reviews on these rusting right away, but because I'm using them horizontally, I'm hoping water would run off instead of collecting on the base. Time will tell.

Easy to install on the deck, but these do not fit 4x4 posts bought from Home Depot or Lowes. The opening is much smaller. We had sand off about 1/16th of an inch on each side of the 4x4 to get it to slide in. Plan on extra work to get the post in or sending them back. Look exactly as they do in the picture and great when complete.

Well made sturdy

These are really made well, easy to install and look great. The bolts that come with them are for concrete so I needed to get some lag bots for my deck. Most importantly, the 4x4’s (pressure treated) that I used needed to be sanded down a little to fit.

Do not fit treated 4x4’s. Ended up having to cut them in half to get them to fit and the provided anchors will not hold up in concrete.
