Ran into this accidentally while looking for PClamps...

Slow boat from china... but still

Double Wire Hose Clamp

Eiji at Datsun Spirit has re-plated originals. I thought that I wanted these too, but found that they didn't have the clamping force that I thought was sufficient. Ultimately went with band style clamps from McMaster.

I've got a box of lightly used ones if anyone is looking.
