Attached you can see the dimensions of 1 of the 3 models we want. If you have anyquestion please let me know.I would like to know the price in stainless steel for high temperature.About the quantity, it will be 500 pieces of the 55mm, 1000 pieces of the 49mm and 200 pieces for of the 70mm.The 49 and 55 has the same dimensions, but they will lock different diameter pieces. If we could use the same clamp for both it would be better, what do you think?
