FOUR Connect 4-690941 M8 ring connector 10mm2, 1 x red
Instead of a normal rubber or plastic sleeve, 4Connect ring connectors come with a piece of high-quality shrink sleeve. A shrink sleeve protects the joint from oxidation much better than a loose rubber sleeve or plastic sleeve.
The connectors are rhodium-coated so that the contact remains good for a long time.
The connectors fit an M8 bolt and a 10 mm2 cable fits the connectors.
