Emmy, They are called Spring Clamp. Mine have a 2 in bite. The number on them is 573-682. Bar code is 8 20909 80002 6. They have colored plastic caps on clamp end & grip end. They are kinda tight but work so well. They have some with smaller bite but you don't want that because it will be too hard to clamp to table. I think they have a 3 in bite one too. Somebody posted about this last year or two so I went & found some. Lowe's didn't have any. Label says distributed by Home Depot. Hope it works for you. I would post a picture but not sure if I can do so on this topic page. Anybody know?
