Why waste your money on those plastic clips. You go to put them on and they bulge out; and when you try to take them off, A Christmas Story is being heard in the back of your head with "you'll shoot your eye out" as the clip goes flying across the room. The clips by Grav are metal. They fit securely for all your glass needs. There is not bulging as they have some give to make it easier to get on and off. But that give does not compromise the function of the clip. you can tug and tug and you won't get your glass pieces apart. So don't just save a dollar getting plastic clips, treat yourself to something nice.
But needs some fiddling and meddling for my uses.
Hi there. We are more than happy to provide some support on the clamp fitting should you need some? Are you trying to connect two adapters with this? If so they should lock nicely. However if you are trying to keep a bowl/adapter attached to your rig, it may need some work. Typically the rig joints are a bit larger. Holler at us at firstname.lastname@example.org if we can support.
