# Mega Clamps?

So is anybody using "Mega Clamps"? The topic came up in another forum and I decided to move it here for further detailed discussion.

So here's what the website says:
-Half the weight of an iron clamp
-Safe vertical working load 600lbs Lab tested breaking strength 2 1/2 tons
-No pan-nut to deal with... a 600# spring loaded washer on the main yoke bolt keeps pressure on the yoke. "This spring pressure keeps the fixture from drifting after making small pan adjustments to the light fixture. Just grab the fixture by the top of the yoke and twist to pan the fixture. Usually, you will not need to pull out your wrench to tighten the pan bolt, the fixture will stay securely held."
-Fits 1-2 inch pipe.
-"micro grooves" in the clamp to hold instrument in place.
-BMI-Techsmart lists price at $10.50... So is anybody using them? Are they as great as they sound? Can you really just grab the yoke and twist and they stay where you leave them? I'm fitting a new theater is it worth a couple extra bucks an instrument to buy these instead standard C-clamps? Original Product Website #### Charc ##### Well-Known Member Run this by me again Gaff. I attach the clamp the yoke, but then it has enough play to adjust pan, but the spring will keep it secure after I'm done adjusting? The two things I'd be worried about, is 1. The spring is inside the clamp, right? Could it ever loose its ability to hold the pan? 2. How well can that spring lock in the pan? I'd be worried about bumping the instrument. Still, sounds unbelievably great. #### gafftaper ##### Senior Team Senior Team Fight Leukemia Yeah Charc, The way I read it, that spring is pushing down with 600lbs of force when you fully crank the yoke bolt down. So you loosen it a little and let it just hold the yoke nice and tight at around 300lbs or so. Stronger and lighter weight than iron. Sounds almost too good to be true. Thus the thread... somebody must be using them. #### stantonsound ##### Active Member I mentioned them in the other forum and have been using them for more than a year, and like them very much. They are very dependable, light weight, and cost effective. They do not feel cheap, nor would anyone have a concern in using them (or at least I can not see why anyone would). It is not a spring, but rather what I would call a "bent washer". Picture a piece of metal that you shot the center out with a bullet, making it kind of cone shaped. You just tighten the one bolt, and then you can give it a tug and adjust the fixture. They do not have the *******nut (whatever you want to call it), so they are much easier to work with. I have actually been selling off all of my old clamps on ebay, a lot of 8 or 10 at a time trying to get rid of them and have switched to nothing but megaclamps and megaclaws. Several of the techs that I have worked with do not use a wrench on them, especially for sidearms and booms. They stay in place nicely, but I still give them a turn with a wrench. They are about$8.90 if you get a good deal from the dealer, and many, many places are using them now. I will get one from the shop and take a couple of pics of how they are used, as I can not seen to find any good ones on line. www.thelightsource.com

The megaclaw is very popular as well. It is designed mostly for moving lights and heavier fixtures. It allows you to hang the weight of the fixture on the clamp and then tighten it. They are GREAT for cyberlights!

As a side note, there are some really cool clamps at www.thelightsource.com. I am thinking about ordering the trusspick, as I feel that it is safer than spansets, and less of a chance of someone rigging it improperly. One of the other rental shops in town has quite a few of the megatruss dolly clamps and they really like them. I made my truss dollies out of unistrut and castor wheels, with 1/2 cheeseboroughs on them, and they will work for me for now.

I will bring some to the first annual Control Booth Convention!

Thanks Tom... I'm going to seriously look at buying all Mega Clamps for my new theater install... The only reason I can see not to is that it's a college and the educational experience of being forced to deal with a normal c-clamp is a good thing. But I want it easy for me too! I'll buy a couple standard clamps to train newbies on.

I should have qualified the post by saying that I am not a dealer, or am I affiliated with the clamps in any way. I think that there are a lot of products out there that are gimmicks, things that sound pretty cool but will fade out. I do not think that these clamps fit in that category. We make our truss out of aluminum, why not the clamps.

Do you mean that you have mega clamps, and that you're only ok with them on PARs?
Either way, the forces on the bolt are the same on both a cast clamp and on a mega-clamp. If you're worried that a fixture will turn under it's own weight, then you need to tighten the yoke bolt. If anything, as a mega clamp only has that yoke bolt (and not the additional pan bolt), they would be LESS likely to turn than a cast clamp.

Pars have the best ballance around the yoke bolt and clamp of any fixture.

There is one MAJOR problem that I have encountered a lot with the mega clamps. They have a tendency to shear very easily if over tightened. The claw part of the clamp is very thin and if you over torque it, it will bend backwards and snap.

I would recommend the L&E Get-A-Grip instead. It is rated to 500lbs and like the mega clamp does not have the swivel bolt. It is much thicker aluminum though. The overall construction more evenly distributes the load like an Altman/ETC clamp does. They are virtually the same price also.

I am not saying all the Mega Clamps are crap, but the L&E is a much superior product in my experience. I always use them with Source 4 PARs, and as replacements when an ETC clamp goes missing.

For more info on the clamp, check out L&E's web site: http://www.le-us.com/accessories.html
