The term "cable eye stiffener" or "wire eye stiffener" refers to a small metal or plastic device that is used to reinforce an eyelet or hole in a cable, wire or rope. This helps to prevent the cable from bending or breaking under heavy loads or stress. Other synonyms for this type of device include "wire rope thimble", "wire rope clamp", "cable thimble", "wire rope sleeve" and "cable ferrule". Each of these terms refers to a slightly different design or material used in the construction of the device, but all function to provide additional support and durability to cable and wire assemblies.
