Unidentified Rigging Terminal

Can anyone identify this type of rigging terminal? It's Stainless, has a brass insert cone and is the most common type on my boat. As far as I know, they're original, which would make them about 30 years old. No markings of any sort. I'd like to know what they are so I can get new cones for them. Someone told me they were a Chinese copy of Norsemans, but they don't look the same externally and I don't know if the Chinese were copying that sort of thing 30 years ago.

Thanks

looks like a stay terminal ( norseman or other) the cone is inserted into the wire with the center wire going through the center of the cone. all the strands should end equal length after capturing cone in center and outer ones are made to encompass cone note: (this is after you run wire through coned nut on right in right hand picture. then you screw it all together and it locks strands/wire in place. the best on the market are the Hayne/Johnson ones now as the cone is grooved to separate strands at equal distance so they get equal bearing

Perhaps they are Gibb terminals?

Gibb, along with Norseman, are both now part of Navtec -- you might try contacting them:

If they are SS you may just want to replace them anyway.

The treads are at risk of crevice corrosion. Halogen salts, especially chlorides easily penetrate the passive film and will allow the corrosive attack to occur.

Once the pitting starts it's all over for strength and corrosion resistance.

Those look very similar to the ones that I have. My boat is a 1976 Aloha 28 and they were used on the lifelines. I'm trying to source new cones for them to install new lifelines. The turnbuckles have "Gibb England" stamped on them. Navtec bought Gibb years ago and I'm talking to them for advice. The tech guy that I reached was knowledgeable and indicated that these could be a few generations of product old and their current wedges may not match.

I'm going to try and post a picture of what I have.

I'll let you know what I find out from Navtec.

They certainly look the same as mine. I've had various answers from Norseman and other rigging sites. Some say they're Taiwanese Norseman imitations, others say they're genuine, but old, Norsemans. In either case it doesn't seem like the new cones will fit, but I've ordered a couple of replacement cones just to give it a go.

According to Rigging Only, these are obsolete and there are no parts available. The new wedges are not compatible. Still waiting to hear from Navtec.

G'Day all,

We ran into the same problem with some older Sta-Lok fittings some years ago. They had redesigned the fittings and the new cones definitely didn't work, and the old style cones were not available. Had to replace the lot of them. Expensive... but couldn't figger any alternative.

Good luck on yours.

Cheers,

Navtec had the same answer - these are 25 years old, obsolete and they have no compatible wedges for them. They did provide me with the corresponding new part numbers for replacement.

Not Sta-Lok, Sta-Lok does not have the counter screw.

30 y.o. very old. Replace, unles on a non critical application.

Those are old Norseman terminals. They are the same as the one's we put on our boat in 1974. As long as there is no corrosion of the threads, they should still be good. The guy who bought our boat replaced the wire but reused the terminals and it's still going strong with them.

Wonder why Norseman changed the cones?? Heard someone bench tested Norsemans quite a while back and they didn't quite hold at the wires breaking load. The wire pulled out at 80-90% of the wire's breaking strength, IIRC, which was plenty strong but not up to what they claimed. Maybe that's the reason for the new design.
