    I need a clamp for technobeams, trackspots, and dataflashes. I would prefer an inexpensive clamp that can hold at least 45 lbs and can clamp to anythng i find in a venue.
    Also, anyone know where to find an original dataflash yoke? All of my AF1000s have yoke, but not the original dataflashes.

    The mega claw is by far my favorite clamp, made by light source. If you are looking for the more standard "altman" style clamp, that will fit mostly anything then go with it, just don't put it on truss and wrench it.

    You've got a third for the Mega Claw. Amazing clamp. Totally worth it. And as soon as you put it, it puts all of the load on the pipe. This is in contrast to the "half-cheeseburger" clamps that require you to flip part of the clamp over the top of the pipe while supporting the whole weight of the fixture.

    Mega Claw is good. I use Trigger Clamps as I have a lot of Aluminum truss. Same concept, the weight hangs first, the you can fix it. Watch out on clamp ratings if you go with a cheaper clamp as movers have a multiplier. (ex: a 45 lb fixture should be supported basing the weight at 450 lbs.) This is due to the fact that the weight can be in motion.

    What about the 2" Snap Coupler by Pro Berger?

    This is by far the best moving light clamp I have ever used. I think this is the way to go if you are in a touring or one off situation where you are putting light on an off truss every day or in a timely manner.

    Anyone ever used the Light Source Safety Clamp? If so, how are they? Seems like something worth keeping in mind for my theater. Maybe it's frivolous spending, but any extra safety in a high school setting seems like a good idea to me.

    I have used them before, they work. The only clamp I have a complaint about from lightsource is the mini clamp. I have a set of JF60's that came with those clamps on them and they are fine if you are hanging down, but trying to hang them on a vertical pipe just does not work. I'm going to try to get these clamps swapped out with probably the mega clamp.

    From what I can see, that looks identical to what I call the "Trigger Clamp."
    I love how their ad pdf has the washer on the wrong side of the latch! I'm sure some guy in design is shaking his head thinking "stupid ad department!" ;)

    And for some reason, everyone I know calls them "gravity clamps" or "pro burgers." I think because you aren't fighting gravity as one would using half-couplers. And Pro Burgers are probably like Kleenex and Xerox.

    I'm pretty sure you've never seen or used the Mega-Claw then?

    Good catch, JD. But how many times has it actually happened that way to you? I.e. washer in the wrong place. For me, it's about at least once every time I hang a show; after the first time, I pay closer attention for the rest of the day.

    You're speaking of the clamping device in the lower left hand corner of this picture, correct? http://tmb.com/products/ProBurger/
    See .jpg attachment. I've only called/heard them called "trigger clamps." They have nothing to do with "burgers" (or "boroughs," if you will). The pdf shows 5 unique devices under the ProBurger name, and the device in the lower left hand corner is called by the manufacturer a '2" Snap-Coupler.' Never heard anyone call it that, either. Anyhow, I don't like them, but would use them if I couldn't afford Mega-Claws.

    I'm leaning towards the Mega Claw, which I have found for $16/each. One final question: what about locations where there is no truss? Random size metal pipes, balconies, possibly ledges, and other misc areas where I don't have the luxory of a normal environment? As there any type of Macguyver type device that will connect to anything I find in the wild?

    Either of these are probably as close to McGuyver as you're going to get. And both are around $8 new and not rusty. The one on the left will rust as it is made of cast iron, the one on the right is aluminum alloy. Since you said your moving lights are scanners and not moving heads, you needn't be concerned with force-loading and using a clamp with SWL of 10 times the weight of your fixtures. But of course, ALWAYS use safeties. I've often hung Cyberlights from these, usually doubled. I've also seen the one on the left break from a neckdown using a 10" Adj. wrench on sched. 80 pipe, while over-hanging a 100 lb. JBL speaker.

    They can be safely used on aluminum truss, with the addition of this: http://www.citytheatrical.com/ "C-clip" Truss Protector.

    Yep, that's the one. Names just seem to pop up locally/regionally, and I don't know from where or when.

    I like them because I am hanging stuff in airwalls a lot, and once you get an airwall hanger up, using that is the fastest, easiest clamp to hang with. The only downside is how long they are. Tends to lower the lens height more than anything else.
