The Trinity Head Balancing Bracket - Gen 1 (THBB-1) is a must for all Trinity Gen-1 users. (Also compatible with the OS360 Upgrade and T1-LIVE)
This bracket set can be used along side the ARRI Skater Tool to fine tune and zero in the balance of the overall rig. With over 15+ different ways of mounting counter weights using the THBB-1, your fine tuning capabilities are endless.
 
First, achieve a Sled Balance via the Trinity 2 Skater Tool Method (balance of the overall rig can still be achieved without the Skater Tool but I find it a worth while step in zeroing in Proper Control of the overall rig and utilizing the THBB-1 to its full effect).
Once optimal balance is achieved through the sled (using the Skater Tool), mount the Trinity Head (without camera build) and achieve a final overall balance of your Trinity rig by using any one of the mounting methods on the THBB-1.
 
-- KEY FEATURES --
Low profile and lightweight to live on your Trinity 24/7
Every production and camera build is different so these brackets are designed to be to be as un-intrusive to the OE head as possible.
Whether you need to run counterweights or not, you wont have to think about mounting or removing each time you prep your rig. Set it and forget it.
