Gibraltar SC-GCSAR Rackpipe Clamp CH

This clamp also comes in a fixed horizontal/vertical version, which is 10€ cheaper.
But I needed this expensive adjustable version because I use it as a floating snare stand holder.
Which requires extra flexibility, in the shape of other than 90 degree angles.

Much is already said about Gibraltar's pricing (recently, they even upped the general pricing of many of their items), but they're one of the top innovative brands, and their clamps are one of the best looking of all.

I also read complaints about their adjustable clamps:
I use several of their SC-GCMAMC clamps as well, but in my experience they're just as reliable locktight as any other.
(the only flaw with the GCMAMC is that it's not perfectly straight 90 degrees in horizontal/vertical angle, so make sure you only use that one if you need the adjustment)

That offset problem doesn't occur with this SC-GCSAR.
It is perfectly 90 degrees angle in horizontal/vertical trim, or with both sides in same line trim.
You can check that with tiny markings on the edges of both moving parts, very convenient.

The clamp is seriously heavy duty. It uses extra metal busses (instead of only the screws) with their own joints that take all the strain in the clamps, the screws just go in those buses to secure. Being fully protected.
They should use this system on all their clamps.

It uses drum screws instead of their usual oversized wings.
The angle adjustment happens on one side with a hex screw.
And at least, Gibraltar throws in an angled (L-shaped) combined drum/hex tool with this clamp.

Couldn't loosen the hex adjust screw at first though. It was too tight for the provided tool key, so I needed a real size rattle tool to loosen it.
That's something to keep in mind when assembling your toolkit, sometimes you'll need a tool with more grip and momentum than average drum tools can provide.

Pricey, but there's not much like it on the market...

But let it be said: the moment you start gigging with these clamps, you will experience the need of covering in any way them during transport in a hardware bag
Otherwise the shiny chrome will splinter off fairly quick.
That’s why I transport them in a mic. bag with dedicated sleeves in it.
