How do I specify final variable spring configuration?

There are three general specifications required when delineating variable springs which would be their type, size, and model. The type would be either a PTP-1, 2, 4, 6, or 8 and the size would range from 00 through 220 and the model would be selected depending upon the attachment in the field by and A through G designation. The detailed information would include the operating load, installed load, movement and in the case of F-cans, the installed height.
