Impact Atom Clamp Reviews

In most cases, fabulous too. But 3 small shortcomings.

By Clayton

I carry two of these in every lighting case and camera bag. My most common use for these is to mount pocket lights wherever I want them. Though I have used them for mounting speed lights, small flags, and point and shoot cameras. Best part about it is I rarely anticipate needing these. But when I need them, I don't know of anything else that would have done the job better. That said, over time there are three instances where these almost helped me. But ended up being no help or problematic. 1) Screw Adapter gets over-torqued easily: Happens enough that these clamps have a companion open/closed mini-hand wrench in the bag. 2) Cannot clamp to small rods: First time I ran into this was when trying to mount a pocket light directly onto a budget window curtain rod. The rod was about 1/8" too small of a diameter for the clamp to latch on. We ended up having to secure the clamp to the road with gaffer tape. To address this shortcoming, I did buy a pair of 9.SOLUTIONS Savior Mini Clamps. They cost quite a bit more. Larger in size. But they do clamp down to any size. So now in my two camera bags, I have one Impact clamp, one 9.SOLUTIONS clamp. 3) No-go with 2x4's: It's surprising how often I end up in spots where I want to clamp onto something made with a 2x4. And this clamp just doesn't do it. Jaws open up about 1/4" too short. And I have to switch over to Super Clamps. Really, I'm being a bit nitpicky in my complaint here. But it was something I didn't think of, and good to be aware of as you buy this.

Would this support the weight of a 2lbs spotlight?
Asked by: Chris
I would say, yes on 2#. I use it mainly to hold GoPro mounts for bike handlebars, forks, tube. I also use it to mount battery packs to light stand. It holds the various mounts and cameras, batteries in the 2# range and manages the vibration of the ride, etc. My opinion is a yes.

how does the ratchet work- and if the clamp is sliding on a pole, then how many turns will it take to tighten?
Asked by: Bruce
You can pull on the ratchet of the Impact Atom Clamp with Ratchet Handle and move it to a position allowing you to provide maximum force even if you cannot spin the handle 360º. You can tighten it down until it will no longer turn; if it still moves, you need a smaller clamp or a larger rod.

Could this clamp be used to attach to the top edge of a vertical piece of plexiglass instead of a pipe, so as to be used to mount a light-weight object to the top edge of the plexiglass?
Asked by: James
Yes, you can use the clamp for your purpose.

question

size of threads of mount?
Asked by: Anonymous
Standard 1/4 20 and 3/8 16 threaded holes. Be warned though: this mount is NOT intended for mounting heavy items. I snapped off the retaining pin on this unit when I overtightened it on a tripod with a SmallHD DP7 on it. I am a bit of an overtightener, but I was still surprised. If you want to be able to CRANK something down and have it hold weight, go with the Manfrotto Super Clamp. A LOT more weight and bulk, but I have never seen one break, ever... I still use this to mount GoPro cams, mics, small lights, etc. But I went back the the Super Clamp for my monitors mounts. Just not willing to put an $1800 piece of gear on one anymore. Good to have a couple in your kit at this price though.
