Question: will this  multi colored umbrella clamp onto my deck railing so I can mount it to cover my weber grill so I can stand and grill in the rain
Document: I ordered two of these umbrellas to give added shade on my deck for plants that weren't protected by my Big Umbrella. Worked just fine, just hooked them railing.
I paid $15 for this, thinking it would easily clamp onto a chair and be able to block the sun directionally. I saw the same item at WalMart for $5...but it's not even worth that. I had one before that truly flexed and bent wherever you wanted it to go, but I can't find that kind anymore. Now I carry a full size beach umbrella with small bungee cords and bungee it to my chair leg. Don't waste your money on this one.
A piece of junk, IMHO. I bought this for some easily portable sun blocking while traveling around to watch lots of summer softball games. It doesn't clamp onto my chair easily. It has a part along the bottom of the shaft that looks like flexible tubing and it was advertised as "sun tracking". It LOOKS like that bumpy ridged part should bend so you can tilt the umbrella toward the sun, but the first time I used it, I tried to bend it and the entire metal shaft bent.
The clamp at the end is a nice size and clamps onto the back of the pool lounge chairs nicely.
Was just like i ordered, it's nice, thank you ! Would recommend it !It came multi-colored, would have preferred to be able toorder a solid color, it's for my husband and his outdoor job.
This umbrella is great for laying out in the lawn, being by the pool, or whereever I may be. It gives great coverage and is super excellent if any rain comes.
Great umbrella for the price. Use it outside on my windy deck in Maine. No problems. Had the first two for one year and ordered two more this week.
This little,light weight umbrella, clamps onto the metal frame of my folding, stadium chair, and shields me from the sun nicely.
This umbrella would not stay upright once it was attached to something. The notch in the umbrella attachment actually matched the shape of the back of our deck chairs and it still would not stay upright. I was very disappointed in this product and submitted a request for a refund for which I got. The sellers of this product were excellent as far as getting it to me quickly and on time and I had no problem with them submitting my refund for this product.
It was fine until I left it out one night in the rain. It rusted pretty badly.
Answer: yes
