Non-coiled 15 ft (4.5 m) long extension cord with Ikelite-style bulkhead on one end and Ikelite-style strobe plug on the other end. Use to position your strobe in a location farther from your housing than accommodated by a normal coiled cord.

Communicates TTL signal when used with compatible strobe, housing and sync cord. The Ikelite-style bulkhead and plug are widely recognized as the most reliable waterproof strobe sync connections available. Built-in strain reliefs reduce stress on cord ends.
