Abstract:
A rope socket comprises a slip cone subassembly having a straight outer diameter and a tapered inner diameter. A plurality of slips is positioned within the slip cone body. A retainer ring holds the slips together. A guide plug is positioned within the slips to maintain the slips in an opening position during insertion of a cable. A spring stabilizer having a spring thereon is coupled above the slip cone assembly to ensure even compression of the spring. A safety slot is located on the body of the rope socket in order to provide a visual indication of the cable position.
