Following my last thread, I was looking to buy some G-clamps to secure my lights to the 40mm goalpost stand.

I have prviously bought a 50mm G-clamp, but it was not very good - thetightening bolt is too low, so you cannot keep it still when hanging. It seems nobody does a 40mm G-clamp.

Anyway, while looking online I saw the Rhino & Pro Light quick clamps - which look really good! It looks like you permenently attach part to the light, and part to the stand, and they just click together!

One thing I noticed though - some ads say it is for square bars only, and some do not mention this. My lighting stand is round, would this be ok?

Also, I saw some old mentions on here that said they are prone to breaking and the light dropping down. However, more recent mentions say they are ok - are they now a different design?

Any advice would be much appreciated!

Cheers, Mark.

I have some of these Rhino Quick Release Clamps and have been using them a few weeks. I have just bought some more. They are much easier to use than G Clamps and don't stick out too much from the bracket when stowing away either. Makes things a lot easier. I use a 40mm T Bar Tubing and found I had to compress the tube slightly using large washers to make it fit snug but have no problem and would recommend them.

I would like to see any negative comments other members may have for long term.

Hope this helps Mark

I've not read of any breakages using the Rhino clamps, but obviously make sure you have at least a thread or two past the wing-nut, and if you have some threadlock, run some of that on before you secure it.

If you are using a lightweight alloy bar, then compressing it will introduce weak spots, so take care.

Also consider a safety wire - they are fairly cheap, and could save a claim on your PLI!

I now try to get the lighting away from the dance-floor, so if a light did fall, it would land away from the guests.
Not always possible, and most of the time, it would wipe Carmen or myself out

Thanks for the advice. I do understand with regards to weakening the bar and It was a concern. I am however keeping an eye on the stress on the Bar for signs of bending etc. I do use safety wires with all my lighting and it is never set up in a position where it can be a trip Hazzard, Usually behind me or to each side of my Speakers when using two Sets of T-Bars. On Larger gigs I use a 16ft steel Truss which would probably double up as an Engine Hoist.

Thanks for that

Originally the part that is fixed to the light was metal with an ABS/plastic shroud. The plastic shroud was moulded to fit the part that is fixed to the T-Bar.

I had one of these break in that the shroud came away from the metal.

The replacement I bought was the Mk. 2 design which had been modified. It had done away with the plastic shroud and was all metal so no chance of breaking.

I have been using these clamps since they first came on the market. They save loads of time.

Thanks Spinner

I assume that any for sale today would be the Mk2 design? I will ask when I buy them.

Many thanks,

Mark

The ones I have just bought were the Mk1 design. I haven't seen the Mk2 yet but after reading about the shroud breaking I will be scouting for them and replacing the MK1's ASAP

Thanks for the info Spinner

Hi guys,

Ive just bought mine - the shop didn't know if they are Mk1 or Mk2 2, but it looks like they are the newer ones.

The "pin" that attaches to the light is all metal, and although the body of the part that attaches to the stand is plastic, the components that "lock" onto the metal pin are metal.

Cant wait to get home and try them out!

Cheers, Mark.

According to what spinner said above I think they're the MK1 ones. as MK2 has no plastic shroud on them.

Don't forget your safety chains/cables!

Cheers,

David

Does anyone have a link for the Mk 2's please. I have googled but the one it comes up with is the Plastic Shroud

Thanks in Advance

Anyone have a decent photo of the part that goes onto the t-bar? The stock photos don't make it clear exactly how part of it attaches to the bar itself!

Cheers,

David

It has to be bolted on (and doesn't come with a bolt).

Thats.... rather useful! I Guess the bolt it only goes so far into the body of the clamp.

Probably would be better if it had a thread coming out of the other end of the clamp and came with a wingnut so you could attach it a lot easier to your truss/stand/etc. :/

Cheers,

David

I did buy a set of these, but ended up returning them.

I prefer using a bolt and wingnut as you can position the light exactly where you want it and tighten it up nice and tight. With the clamps, the light could still "move" slightly, although it seemed safe and unlikely to fall off.

Also, remember the bit that fits onto the light might stop it from fitting in any flight cases you can (my main reason for returning them).

Finally, they are no good for mounting lights "upside down" above the T-bar, which I sometimes do.

Hope this help,s

Mark

Hi all

Interesting comments made by some, I use these

http://www.bluearan.co.uk/index.php?id=RHI...semode=category

I keep them permanently attached to my lights and they simply clamp round the round section of my truss and secure using the wingnut, no crimping of the tube section, as with a nut and bolt and not reliant on holes pre drilled into the truss, they can be mounted underneath or above and come with adaptors to fit different diameters of tubing (trust me i'm not trying to sell any!)

The only gripe I would have is that if you are using a heaver light fixing the clamp does not grip too well around the br and so I use a length of insulation tape fist as a cushion then it grips nicely, although I always use safety cables wherever I play!

MAy be of some use

My clamps are fitted to a pair of Transcenscion Light Bars. I bought a length of threaded bar of the correct gauge and cut a number of pieces to size. I screwed those pieces into the pre-drilled holes on the bars then simply put the clamp parts onto the protruding bits and screwed them on.
