4 x 4 Post Base 5PCS,Inner Size 3.6"x3.6"Deck Post Base,Heavy Duty Metal Black Powder Coated Post Brackets,for Mailbox Post Deck Supports Porch Railing Post Holders

The anchors that I received were 3/8 inch in diameter, not 1/2". I pre-drilled the holes based on my partner having the same ones. His came with 1/2 in anchors. I needed to complete the project, so I had to buy 1/2 in diameter anchors.Extra expenses!!!Edit: The post bases do a good job of holding the 4x4 post snug. I used them to install a heavy gate. The posts rest in the post bases and I added an L brace at two points on the post.I used the 1/2 in. anchors I bought instead of the 3/8 in. they supplied. The 1/2 in. anchors filled the holes in the base very tightly. If you are using a handheld hammer/drill, you should use the 3/8 in. anchors. I had a hammer/drill guide so that when I started the hole the bit would not jump around. By hand, any slight deviation and the bases have no give in case you drilled the 1/2 in. holes a bit off. The product and customer service were perfect for my intended use, 4 starts instead of 5 because the anchors were not as advertised.

These are new, so I can't speak to durability, but I bought some others that were garbage. I paid my handyman to put five in for a handrail. They were so wobbly, I had these delivered overnight. These seem very secure, and my handyman said they were easy to install. He's building wooden bases to cover up the screws and make shoveling easier. Now I have three extras, because they come in packs of eight. Only disadvantage I can see.

Thanks

Product is great, makes a seemingly tough job easier. That being said, all four sides have holes for 2 screws to secure the 6x6, so 8 screw holes- only received enough screws for two holes on each base, this leaving 6 holes open. The 6x6 is NOT secure with only two screws. Additional screws will need to be purchased. This quite literally screwed my day.

Top part moves (flexible), so can't tie curtain material between them using rope or posts will lean.Good for fence post construction

The product works as described, but it does not hold up to weight very well. I have only had it a month with the 4 x 4 inside and the bottom has already cracked. Wish it was a little more sturdy.

4x4 studs fit real loose in these bases. They are for light to medium duty projects. The bottom of the bases are open. I had to manufacture some plates to cover the opening.

Purchased this to hold a 6 ft 4x4 clothes line pole. The base attached securely, but flexed enough to allow the pole to wobble. Used guy-wires to eliminate the wobble. Wonder if a shorter mailbox pole would also wobble?
