Our Tilter Bracket included with the Spiderlite TD6 works with most manufacturer's umbrellas and light stands. The Spiderlite TD6 also has a built-in speedring for use with all our Pro and Pro Signature softboxes, excluding Octabank and Zeppelin. The Spiderlite TD6 will also accept most other 3rd party softboxes that utilize the standard 4-rod mounting system.
