This is the Ikelite Dual TTL Sync Cord for Two (2) Ikelite DS Series Strobes [4103.52]

Y-shaped sync cord with Ikelite-style plugs on all ends. Provides TTL operation with any compatible system featuring an Ikelite-style electrical bulkhead and two DS strobes. The Ikelite-style plug is widely recognised as the most reliable waterproof strobe sync connection available. Built-in strain reliefs reduce stress on cord ends. This cord requires the attachment of two strobes for waterproof operation. To shoot with only one strobe, try a single sync cord instead.
