The RB-5039 Quick-Release Plate for B-Series Ball Heads from Redged is a direct replacement for the original quick-release plate that's included with the RNB-2 ball head. Because B-series quick-release plates only vary in length, any B-series plate will work with any B-series ball head.
Fits any B-series ball head
