Thunderbolt 3 Cable. ThunderLok 3.

Sonnet includes a 0.5-meter Thunderbolt 3 (40Gbps) cable that supports Thunderbolt 3’s full 2750 MB/s PCIe bandwidth. Sonnet also provides a ThunderLok™ 3 Thunderbolt connector retainer clip(3) that prevents accidental cable disconnections—just slide it over one end of the cable, and then plug in the connector and secure it to the chassis by turning a thumbscrew. Because of its unique design, ThunderLok remains on the cable so it won’t get lost when not in use.
