Female Ground Joint Holder

Griffin Glass Tools ground joint holders are top notch! They have made the handle out of stainless steel, but they have had it textured for more comfortable handling and smoother rotation. The graphite is of super high density and made to hold up to harsh working conditions. The sizes we currently offer are 10, 14, and 19mm male and female holding tools. (For reference, the tools are named for the glass shape that  is being held, not the shape of the graphite on the tool!)
