Your goal is to determine the information required to make up the ordering code or part number. An example of a typical ordering code is 173-VTG-3-144.

173 - V   TG - 3 - 144

Step 1: 
Determine the "duty" (size) of the cable by the diameter and threads of the end rods.
V = 10-32, L = 1/4-28, M = 5/16-24, H = 3/8-24. (Very light duty; Light duty; Medium duty; Heavy duty)

Step 2: 
Determine the type of conduit end fittings (conduit caps) for left end and right end.
T = Threaded, G = Grooved. TT, GG or TG combinations.

Step 3: 
Determine the travel of the end rod. 1" through 6" in one inch increments.

Step 4: 
Determine the overall length of the cable.

Step 5: 
Determine cable materials depending on usage and conditions. See details of 173, 174, 175 Utility and 313, 314, 315 Low-Friction EXT.

Utility: The Rugged Gray Cable, is the industry standard and is designed for a long life under rugged conditions (173, 174, 175).

Low-Friction EXT: The Green Cable, is the proper cable to use when superior efficiency is required. The extruded nylon cover over the innermember works extremely smoothly with the poly liner (313, 314, 315). 

See Push-Pull Cables section to determine part number.
