Male Ground Joint Holding Tools - Griffin Glass Tools

Our ground joint holders are top notch! We have made the handle out of Stainless Steel, but we have had it textured for more comfortable handling and smoother rotation. The graphite is super high density and made to hold up to harsh working conditions. The sizes we currently offer are 10mm,12mm,14mm, and 18mm Male and Female holding tools. (For reference, we named these tools for the glass shape that is being held, not the shape of the graphite on the tool!)
