Get double the rotation with the GRAV® Large Circuit Rig. The angle of the intake hole causes water and vapor to spin rapidly and form a powerful centrifugal force. This cools the vapor and makes each hit smoother, and the twin stacked chambers multiply this effect. There's no need to worry about splashback with the Large Circuit Rig, because the sharp bend in the mouthpiece keeps all water inside the rig. This piece includes a 14mm female-jointed domeless nail made of heat tolerant quartz, so all you have to do is add about 0.5" of water and then you can get right down to the fun stuff. The labels for this piece come in assorted colors. You may receive black, white, blue, green, red, purple, yellow, orange, or etch.

Great low priced rig!

My lady friend and I liked this so much we bought a second one to have at her place. We both recommend them highly

Second one I've gotten. This one the holes are bent to the middle so it does not really spin or filter the smoke through the water. It just bubbles alil. Was kinda blown actually. First one I had worked amazing.

Greatest Piece on Earth

I’ve beem buying this piece for years (due to my own clumsiness) and I’m so glad I could purchase directly from Grav! Everyone knows Grav Labs does the best glass in Texas and the world and this rig is no exception, I love it for so many reasons. It’s small but packs a powerful punch, it’s not too complex and hits smooth, and this version I just received had the best mouthpiece I’ve experienced. It kisses me.

Customer service is Excellent, The Glass not so much.

I used to love grav, and have always purchased there products at my local certified syndicate. The glass had been in front of me and I could see what I was getting, and was always satisfied... until I had a beaker crack on a seem at the bottom of a 24 hour old beaker. (It ripped great the one time I used it. Till I woke up to a wet mouse pad and a near empty beaker. I always have my glass organized on my desk. Any how, customer service absolutely killed it and simply needed photos of my recent proof of purchase and the cracked seem and they credited me for the value of the beaker. I was an idiot and got the “large” straight tube because 1 i would have to worry About a seem on a beaker again 2 it was on sale and I could get another piece with what I had spent on the broken beaker. So I got the “large” circuit dab rig as well and payed a minuscule amount on top of my credit. The straight tube hits fine for little tokes, the rig you can get a rip on but it is tricky to handle due to size. For two Large products, I was very surprised by the scale of the glass. They are quite small and I should have looked more into specs but the title “Large” is an overstatement. Other than that they are great looking and functioning little pieces. I suggest the beaker, even though mine was faulty I regret not just ordering the same thing. I’m sure it’s a rarity for a break like mine to occur. All in all I’m still a huge fan and supporter, and can’t get over the quick and efficient customer service.
