Secure Connection Assured

Thunderbolt 3 connectors are held in place by friction—which usually works fine in setups where your gear remains protected from disturbance while operating. But, if there’s a chance of movement nearby, it’s possible the Thunderbolt cable can be accidentally disconnected, leading to the loss of a file or an entire project. Sonnet’s ThunderLok 3 Thunderbolt connector retainer clip was designed to solve this problem by preventing accidental cable disconnections from many of Sonnet’s Thunderbolt 3 products.

To use it, simply slip it over the cable connector, and then plug in the connector and secure it to the product by turning a thumbscrew. Because ThunderLok 3 doesn’t attach to the connector, it stays on the cable and won’t get lost when not in use. Sonnet already includes a single ThunderLok 3 with many of its Thunderbolt 3 products. ThunderLok 3 with all 0.5-meter Thunderbolt 3 (40Gbps) cables, and 1–2 meter Thunderbolt 3 (20Gbps) cables.
