A cord grip to grip 2 core electrical cable into chassis.

I designed this for a JVC JA-S22 amplifier I'm working on which is missing it's cord grip, but it's likely to fit in other amplifiers and general electronics.

You can trim the cord grip part using some cutters if you don't need as much grip or it doesn't fit.

It is 14mm diameter at the outer edge and fits in a ~12mm hole in the chassis.

It's not a masterpiece but does what it needs to do well.
