This is an excellent product. This is my second Railhookz deck clamp. The first one I bought in 2019 and it is still going strong. One of the clamp pieces with the square holes had only one hole punched out. I used a hacksaw to take off the little nubbin, then finished off the opening with a metal file. Rock solid, easy to install. Great value for the price! Thank you.

So I purchased this mount in 2018, wow. This year, 2025, I decided to purchase a new one as the current mounts screws were rusted. I searched my Amazon previous orders only to be surprised that they still sell the exact same one. *Super Siked*I have kept a patio umbrella every year since 2018 just replacing a new one into the current mount.This mount is amazing! It has lasted through years of storms, winds, rain, you name it. And it could go for a few more years but for the price, I’ll just replace it. GET IT! Very sturdy, extremely durable, and definitely worth it.

Attached the support to our dock for an umbrella. Worked great but i added a piece of rubber busing for extra grip.

I’ve purchased a lot of things on Amazon over the years but by a mile this clever device is my favorite purchase yet. I’ve included a couple of pictures of two I purchased a few years ago. They look brand new after being outside for a few years. I’ve replaced the umbrellas several times, but these mounts are unblemished. They are especially effective in holding the umbrella stable, even in such a high wind area as my top floor deck. I purchased a third for my lower deck and was able to install it in less than five minutes. The designer was very clever in his choice of using wingnuts, and a bolt that has a square head which fits into a square hole so the bolt doesn’t spin when you tighten it up. The attention to detail on this design makes it my top Amazon choice of all time.

I can't sing enough praises for this product. It's rare that you find something so simple that so perfectly meets your needs and so inexpensively.My balcony is about 4x18ft and gets a lot of direct sunlight throughout the day. I didn't want to waste space with a bulky umbrella stand and this allows you to perfectly mount an umbrella to the railing (obviously double check your measurements - it won't work with all railings, but as I recall the description is very clear on compatibility).Im on the second floor, so for the first few months I kept the mount on the inside of my balcony just in case it every slipped and fell it would land on my balcony. After many rains and heavy winds, I was pretty confident I could keep it mounted to the outside to save even more space and so far 0 incident.I'll probably eventually get 2 more of these so i can easily move my parasol along any portion of my balcony.

I have a deck that receives full sun after noon & I wanted an umbrella for some shade but the deck is small & the bases have such a big footprint. I was so happy to find this, it's such a great idea! It was very easy to install (it did come with some instructions), it took me maybe 5 min. to mount it to the deck rail & get the umbrella set up. It is so sturdy & is awesome for my umbrella, I can now enjoy my deck in the afternoon & evening without being baked by the sun!HOWEVER... even though I had tightened the bracket that holds the umbrella as tightly as I could, it apparently was not as tight as it needed to be because on the second time having the umbrella open on a windy day a gust of wind lifted that sucker straight up in the air & up over the roof of my 3rd floor condo! It looked like something from Mary Poppins!! After the initial shock wore off it was quite funny, it got stuck on the roof & I finally had to call the fire dept. to retrieve it before it came down & did damage to property or people. So I had to figure out another way to make sure the umbrella pole was secure. I thought the smooth aluminum of the pole against the metal bracket didn't have quite enough friction to keep it from being lifted so effortlessly by the wind so I thought some type of grippy rubber might work. I found some of those gel heel guards for women's shoes, they are the perfect size strip to fit in the bracket & actually allow me to tighten it more... that umbrella feels VERY secure now & I think the rubber is the perfect thing to make it even more so, I seriously doubt that it'll be taking off again! I think I'll suggest to the manufacturer that they should add something like that to the design, the bracket honestly is a great invention!!
