GRAV® Large, Clear Circuit Rig

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.

good glass

The best rig I have ever purchased. My only complaint is that the nail included broke in a few weeks while I was heating it. I would honestly recommend a ****** or higher quality nail to replace it with for lasting use, but the rig itself has been my tried and true piece for months!

Years of loyal service

I’ve purchased this rig for years, going as far back as 2015-2016. I also break it once a year like clockwork. I’ve bought 5 so far from various sites but my last two directly from Grav which is far preferable. I love the company, I love the craftsmanship. I trust the glass. It’s my own fault I put it in precarious situations requiring me to replace it but I wouldn’t spend $80/year if this weren’t one of the best pieces I’ve ever had. Not too difficult to clean, solid pull, minimal water required, versatility!

Don't know.

I couldn't review the item because it arrived cracked and the replacement they sent was the wrong item. Customer service was not very good.

Perfect dab rig

Smoothest dab I've ever taken, my roommates prefer this rig over their own.

Nice rig

The rig itself is pretty nice, but the nail broke within a few days which was pretty annoying because this was a replacement from my other grav piece that broke before this.
