V anchor stainless steel grade 310.
Diameter depending on length:
2'' & 2.5'' = 1/4''
3.5'', 4'', 4.5'', 5'', 6'' = 5/16''
In order to determine the length of the anchor, the rule of thumb is to subtract 1.5 inch of the total refractory thickness. For example, using 6 inches thickness of materiel, we recommend using 4.5'' V anchor.
