Fid not get the 30 mm screws that are described. Had to use my own screws. I did receive the 20 mm ones, but not enough for all 6 post holders.

These are going to work great for putting 4x4 posts for our carport on the concrete pad. They are made well and should last a long time. They are heavy made and look nice. Overall pleased

Fnxaor 4x4 Post Base arrived nicely packaged and without damage. I did not find any part that required repair or touchup. All hardware was easily identified and the dimensions matched the product description.Installation was extremely easy and I had my project completely mounted and secured within minutes! This post base functions exactly as intended and the black finish matches other hardware of my project. I feel it is a great value for the money and very competitive to big box store fence post bases. I have seen some with additional screw holes, but if I feel it needs it, I can easily drill the base and add them. I am happy with the product and result!

Nice post base. Arrives wrapped to protect its powder coated steel. Attractive and complete powder coating. Outer base corners are rounded. I measured inner opening for the 4xc4 at ~3.61 inches per side on both upper and lower ends. When fit to a nominal 4x4 post (3.5" x 3.5"), I would have visually preferred a slightly tighter fit (see pictures), but appreciate that this base's dimensions will better accommodate post size variations. Finding color matched caulk will address the visual fit. Comes with color-matched screws: 4x larger screws for attaching the base bottom, and 8x smaller screws for attaching the 4x4 post into the base (2 screws per side). Ready for a deck post!
