I need to buy the cable for this system . 15mm nylon coated rope hidro. ESCO P-9 Holeless.

Try web rigging supply on the net. I cant believe there are still some of these in service. I repacked 2 of these units on the American Queen River boat when it stopped in my city. The boat was on its maiden voyage from New Orleans to Pittsburg and stopped in ever town on the way that had a local Otis office for A repack! 1st and only 1 I ever saw thank goodness!

I've only seen pics myself. I'm very curious, how did this system even work?

Yes ,I have two units here in Puerto Rico, the problem is the rope wear.

Not sure where you can purchase that rope. Several years aago, Otis had some made. It was worse than what we removed. They had another batch made, same results. Seals are availble from Texacon but again, better order several because thye don't fit right either. Best advice, run.

Thanks to everyone, Otis have a very high ridiculous price.
