This version of Ikelite's 3' Extension Cord has replaced nickel-plated brass fittings with anodized aluminum ones, achieving significant weight reduction without sacrificing durability. Fitted with an Ikelite strobe connector at one end and an Ikelite bulkhead connector at the other, the cord allows you to position your strobe farther away than your coiled sync cord will stretch. The extension transmits TTL signal in compatible systems. The cord has built-in strain reliefs to reduce stress on cord ends.
