About this item

  • Material:304 Stainless Steel,Black finish;
  • Actual inside size:3.58×3.58inch(91×91mm);
  • This package come with 16 Pcs 5/16" hex screws and 32 Pcs 3/16" screws,all the screws are made of stainless steel and can only apply to wood base;
  • Note: 4x4 wood post’s actual size depends on the wood type and dryness. We made inner diameter 3.5x3.5inch square anchor base according to the genral size of wood. We believe in very rare cases post actual size is larger than 3.5inch. In this case, we can try sanding and triming the wood post, to match with the inner size of the post base.But if we made the post base size over larger than 3.5inch, there will be a gap between wood post and the base, which is difficult to fix.

I used these for a railing on my dock. I was amazed how solid the posts were. I like them a lot.

These are quality made and the included a drill bit for pilot holes. The drill bit and bolts worked flawlessly. I would buy and install again and I would recommend them.

I was somewhat unsure of how well these would work for my application, but they far exceeded my expectations. These worked great for the "picture frame" design of the cedar decking. It is important to note that the lag bolts you use to attach to the decking needs some additional support underneath. On the decking, we were able to go through to the 2x6 joists below. On the stair bottom, we added a 2x6 plate to sink the lag bolts into. Would buy this product again.

As title says this product was really easy to install and it looks nice, has a nice finish to it, it's sturdy and with just a little care I got it all very straight. I built a small privacy fence with it for my deck up near my house and I'm happy with the results.

This is a cross product review, to include all the tools,etc that I used to build my deck:I built a 32 ft x 32ft deck with composite boards (purchased elsewhere - HD-Veranda 16ft boards)The rail posts I used 4x4x36" code requirement for my area, and 1/8 stainless steel cable, set 4" apart.For the rails, cabling, etc I purchased it all on Amazon:- Antsky 4×4"(Actual:3.5×3.5inch) Wood Post Stainless Steel Flange Anchor Base: these came with all the necessary screws and a drill bit to get the job done. These are very solidly built. To be sure these were fastened properly to the deck, "2 by" planks where attached to where the posts would be affixed.- BLIKA 60 Pack T316 Stainless Steel Right&Left Handed Thread Swage Lag Screws for Wood Post of 1/8" Cable Railing Kit: this was used to fasten the cable to the posts, it's an affordable solution to the "hidden" screws. I had "rails" along 3 sides of my deck and used these at each "end". The posts were placed about 45" apart from each other. Be careful when crimping the cable to these that you don't over-tighten or they will bend a little. The tool that came with it works well, didn't bend or give any other issues, I would wrap electrical tape to be easier on the hands when using the tool.- HTWR 1/8" Deck Cable Railing Hardware with Cutter: This is the cable I used, looks good, very strong. This is a wait and see how long they will last without rusting (shouldn't since it's advertised as Stainless Steel). The cutter that's included works well, no need to buy a separate one. It also includes gloves, which I didn't use. I have leather gloves.- Bonvoisin Hydraulic Wire Crimper Battery Cable Crimper: Wouldn't have been able to complete the job without these. In my case I used die #6 and it worked great. I did crimp it 3 times on each end to ensure it would hold. This is a simple tool to use after you get the hang of it. The way I did it was to close the crimp around the middle of the "swag lag screw" just enough to hold it in place, then slipped the 1/8 cable in and crimped, repeated this 2 more times for each screw.- CKE 80 Pack T316 Stainless Steel Protector Sleeves for 1/8" Wire Rope Cable Railing: These are for looks, so that the cable, doesn't go directly into the wood post, but they do make the railing look much better. With these I drilled a 1/4" hole end to end on the middle posts. Inserted the lead side prior to running the cable. Once I was ready to run the cable, I fed it through the hole, then added the other sleeve into the hole and tapped it with a small mallet to get it into place.All these products were top notch. I did take a while to read reviews and specs and for my specific project the above are what I found to work best.
