stonylab Plastic Joint Clips, 10 Stuks 29mm Lab Keck Clamp #29 Keck Clips voor 29/40 Joint Glass Standaard Conische Interface Clip Ground Glass Joint Lab Accessoire, Rood

If you are unsure of your specific sizing needs, buy the multi-size pack and then get the perfect size for your chalice or rig. I tried two different clips from the multipack before I knew what size I truly needed. These specific clips fit perfectly on my glass (14mm bowl with 18mm stem and larger outer glass with the most common girth, not sure of the actual mm) and are very durable. Keep a few and gift a few…be a hero!

This is a great product to create a secure and reliable connection between sections of 24/40 lab glassware.

I received my order but the items are only 4 pcs which should be 10 pcs per pack.
