    In accordance with API-2C, values shown are acutal hook load (weight of block and hook excluded).

Load line block weight is 3200 lbs.
Load line (6 part line): 1 1/4" Dyform 18 EIPS-IWRC; 175,800 lbs. breaking strength; 35,160 lbs. working strength.
Fast line block weight is 210 lbs.
Fast line (1 part line): 3/4" 19x7 EIPS-IWRC; 48,000 lbs. breaking strength; 9,600 lbs. working strength.

Static load = 1.5 x dynamic load
Pedestal reactions are based on three times the dynamic load plus the dead load.
