1/4" 3/8" Thread Rod Clamp Rail Block for 15mm Rod DSLR Rig Rail System Follow Focus

This little jig works perfect. I'm not sure why people are bringing up the fact that it only locks on one side. It makes know difference, it locks and it locks well. I am using a 7" monitor on it with batteries on the back and it doesn't budge. It does exacly what it is supposed to do.

This little bracket does the job well. It's solid, slides nicely on my rails, and the ratcheting thumb screw feels like quality construction.There's only one reason I didn't give it five stars, and that's that the distance between the two rail slides is a tad bit wider than spec, about a millimeter long. I can fit it on my rig just fine, but if I try to slide it up against any of my other components it binds. If you look closely at the first photo, you can see the slight misalignment between this Pangshi thread rod, and one of my rig components.Pros:Solid constructionRatcheting thumb screw3 1/4" threaded holes and 2 3/8" threaded holesCons:Rail holes aren't exactly the right distance apartWould I recommend this attachment? Sure would!

Bought this to mount my tablet to my rail system. It works great and tightens nicely. I might get a few more to attach other things to the mount system!

Terribly made. The threads are thin and cheap, and the tightening gauge snapped off on the first turn. Avoid.

Look carefully. There's only ONE side that can be tightened. I was planning to use 2 of these to lower a 2nd set of rods down on the front end of a camera and mount a small teleprompter rig to them. But then I realized it won't tighten on both sides. Well, that means this is only useful if it is laid out horizontally on your rails. And even then if it's something that may get some torque or tension, this is not going to be the best thing to hold it in place because there's only 1 SCREW. I kept them because they were inexpensive, but for practical purposes these are not the best option in every circumstance unless it's very light duty stuff you want to mount on your rig.

It fits but it never seems like it fits well. I have to grind down the locking mechanism before I feel confident attaching anything to it. I have a feeling the plastic knob is going to break in about a year. The rest is decent metal and it will last quite a while.

This bracket does the trick. I have had other adapters to try and hook my monitor up, but my monitor always came loose with the magic arm and the adapter that was supposed to work didn't. This bracket does an awesome job! with keeping the monitor secured and tight so your monitor doesn't become loose and fall .

I loved it, the material, the construction, its the perfect item for holding a matte that i had. And the price is excellent. 100% recommended.
