Westcott Triple Threat Speedlite Bracket
Designed by adventure photographer Bruce Dorn, the Triple Threat Speedlite Bracket from Westcott allows you to gang 3 lightweight shoe mount flashes for use in a softbox or umbrella. Most speedlites in this category output about 60W/s, but with the Triple Threat you now have an approximately 180W/s flash with the power of a small studio head and TTL options depending on your choice of flash.
The Triple Threat is made of lightweight but durable polymer with metal shoes with knurled locking knobs. The center hole is made for all standard umbrella shafts or you can use the 1/4"-20 tap to secure it to a bracket or other type of compatible gear.
