Zipbolt14.110 Super UT Newel Post Fastener — Quick and Easy Wrench-Free Installation of Staircase Newel Posts, Anchors Post Directly to Wood or Concrete Floor

I don't write many reviews but I hope this one will help someone installing this in concrete. The bolt works great, the post is solid once tightened. I had a hard time gathering information to find for concrete installations so I'm going to explain how I did it:If you're installing in concrete, make sure your bit is an 1/8" bigger than the diameter of the bolt. Drill down as far as mentioned on the directions. Clean out all dust from the hole with a shop vac, brush, bolt, etc. Get the dust out completely, then I used the following epoxy:Sika Anchorfix-2, super strength anchoring adhesive, Two component anchor system for threaded bars in uncracked concrete, 10.1 fl. Oz https://a.co/d/2JaAc69Filled the hole up about halfway, then filled the threads on the bolt as well. Work quick, the stuff sets in 4 minutes. I waited a day before I put the post on a tightened it down. Hope this helps someone.

Worked great. Watched some YouTube videos on how to install and it is exactly what I was looking for. Very sturdy and worth the money. I would buy it again.

Super easy to use, great holding strength! Once you drill the holes in your post, it takes only minutes to put in place.

First, I'm very satisfied with the results of my project. My railing posts are very secure and I believe they will hold up for many years.While the instructions were clear and the product was easy to use I wished that the company website or product packaging had more information on how to secure the bolt in a concrete floor, which my situation required. A concrete adhesive (the kind with two tubes of product you mix together that sets in about five minutes) worked but I had to research elsewhere and was very nervous about using a quick set epoxy that I wasn't necessarily sure would hold.The ratcheting gizmo is a neat design. It didn't matter for operation but I did find it odd that the bolt threads were opposite of normal (lefty tighty, righty loosey) and I had to keep reminding myself to turn the ratchet the "wrong" way during Installation.I felt that the price was high for what's essentially a lag bolt and fancy nut but I do have piece of mind that no one will tumble down my stairs.One more aspect that I like is that if you ever need to disconnect the newel post from the floor it can be accomplished by drilling out the wood plug, which would enable you to reuse the expensive hardwood post.

It was fine. The package was partially opened but everything was there and worked perfectly.

I purchased 2 units. Only one of the units worked. I nearly ruined one post trying to get it to work. It would not tighten or loosed to be removed. I spent a bit of time getting it off. A real pain. After getting it off, I checked for cross treads and found none. I did not have time to order a new one, so I disassembled and attempted to repair. The gears were very rough and burred. I filed smooth what I could, but it still did not work well.I did used it, but it never tightened down well. I had to put long screws through the floor from below to hold the post. I thought these would make my job easier, but I was wrong. The quality is hit and miss. I will not take a chance on these units again.

Item worked great.

Wow worked great. Best I've seen
