You can buy rope at a local home improvement store and make custom cable attachment ropes up to 1-1/32" in diameter. Rope can be terminated by tying a knot at each end to prevent hand slippage.
This swivel can also be used to make custom steel cable attachments with a rotating swivel using a 1" OD cold rolled steel bar. Simply grease it up before installation and then install a pair of 1" ID shaft collars on both sides of swivel to keep swivel from sliding back and forth on bar.
