Grav Labs - Ground Joint Clamp
This ground joint clamp from Grav Labs is made of durable acrylic and is designed to secure your glass-on-glass parts together at the joint in order to avoid easily-preventable accidents. Try using one to secure any two parts together more permanently, or use to secure your downstem to your tube's joint to keep it from moving around when you lift your slide bowl during a hit! Choose from a 14.5mm, 18.8mm or 29.9mm joint size when ordering.
- Good Clip! Review by Dr. Spaceman
OverallI had never used a bong clip before and wasn't sure how easy it would be to work with. Turns out they are incredibly easy to attach and detach. I've got no worries when this things on, I use it to connect my Blaze 11-arm precooler and Black Leaf j-hook. It keeps an airtight seal and doesn't allow for any movement. It's very useful and at a good price. Arrived 3-4 days after shipment, which was fast.
