Hi again,
I had a lovely conversation with Craig Pugh, an engineer at Electroline regarding their fittings. They do indeed make them for 1x19, and you can get details on pricing and world-wide distribution by writing to: Kobi Briggs
. You can also visit their web site: www.esmet.com.
They didn't have efficiency numbers regarding ultimate strength, but Craig was confident of 90 to 95%, about the same as Sta-Loks.
Being an industrial house, they weren't up on the effects of the corrosive environment that a sailboat might see, especially in the tropics, but some of their clients do add sealant. I expect that you could seal the interior of yours, as with other terminals.
Materials and finish are both very good. Prices are very, very good.
Overall I have a most favorable impression of the company and its products. In the case of your boat, I strongly recommend disassembly of all terminals to check for internal corrosion, and to see if they were assembled correctly.
Fair leads,
Brion Toss
