|Simple way to measuring chains
Length (I) - Not more than 5 times and not less than 4.75 times the size
Outside width (w) - Not more than 3.5 times the size, except at the weld. At the weld,
not more than 1.05 times the adjacent width.
Pitch (P) - Length I - 2d=Pitch of Chains
DIMENSION OF LINKS
Various grades of Links Chains & Safe Working Loads.
L = Grade-30, M = Grade - 40, S = Grade - 63, T = Grade 80
