These clamps work great. I needed them to mount my base station antenna to a 1 1/2” pole.

As an amateur radio operator, I was looking for something that would allow for easy mounting of multiple masts for different antenna applications. I ran across these and decided to give them a try. These are the perfect solution to mount an additional mast towards the top of the tower. It allows for a firm grip to the tower and does not extend out too far, allowing the mast pole to be closer to the tower. The teeth are nice and will do a great job holding to the tower as well as holding the mast. The material appears to be of good quality and should hold up for many ears to come. The only downside I have seen is the clamps use a wing-nut to tighten. While this will be appropriate for most applications, I prefer an actual nut that can be tightened with a wrench. In time, I may trade this out for a nut instead of the wing-nut. Overall, I am very happy with this product and would recommend it to anyone needing a similar application.

These are good light to medium duty mast to mast clamps. I would recommend a few changes though. I would replace the wing nuts with conventional nuts and split ring washers. Otherwise, they will loosen up over time. I would also add a two more sets of nuts and split rings so that you have more flexibility in mast spacing and tensioning. The coating is a heavy paint or cold galvanizing and should hold up well in the weather. These clamps are a decent value and just what you need for mounting tv, cb, or small to medium ham antennas.

Update (2/8/25): Additional observations: 1) the silver coating is not very durable, it feels like paint; couple of the pieces arrived scratched from rubbing around during transit; 2) the thread size is listed as 5/16", but is actually M8. 1-star, product information is very inaccurate.Summary: I am going to re-use some 2" aluminum pipe to build a ground array, solar panel rack.

I purchased these Double Antenna Mast Clamp V Jaw Brackets to secure my telescoping flagpole to the ladder on my motorhome, and they’ve been fantastic! The clamps are solid, heavy-duty, and appear to be of great quality. I’m confident they’ll hold up well over time, even in outdoor conditions. They’re easy to install and provide a secure, stable mount. These clamps are built to last and I would highly recommend them for anyone needing reliable mounting hardware for antennas, flagpoles, or similar setups.

I ordered this double mask U bolt kit so I can mount some additional weather instruments to my weather station pole (See pictures). The pole cemented into the ground is 1-3/4 inch in diameter, but I needed 1 inch & 1-1/4 inch diameters for the two additional weather instruments I am going to add to this pole. These brackets work perfectly for this purpose.The brackets are well made and the U bolts are bent perfectly. The finish appears to be galvanized but whatever it is, it seems fairly durable and should last outside for quite a while.I did add several M8 hex nuts that I had to this kit. It made it easier to mount the additional poles how I wanted them and also enabled me to space one of the poles farther away from the main pole.The price for these kits is reasonable and I would highly recommend them if you have a project that needs this type of brackets.

These clamps can combine two poles together to make one longer pole. The clamps work well, as I was able to securely join two poles together. installation was simple. The clamps could possibly be made better by using locking nuts vs wing nuts, i'm not sure the wing nuts will not loosen over time. Overall construction feels sturdy and should last a long time.

Good product! Good galvanized coating and a nice smooth finish. These should last a long time. I used a pair to install a crossbeam on an upright mast and they worked beautifully. I did, however, replace the wingnuts with a standard hex head nut. Just seemed easier to work with than pliers and wingnuts.
