CB Buttons are recommended for use on 6x19 or 6x37 IPS or XIP, EIP, RRL, or IWRC wire ropes. Not all CB Buttons are designed to hold the breaking strength of the wire rope. Before using a CB Button for any type lay, construction or grade of wire rope, it is recommended that the termination be tested to prove adequacy of the assembly in the intended application. Proper swaging practices are the assembly manufacturer’s responsibility.
