This sale is for a really excellent condition Mamiya RB/RZ67 Tripod Adapter 3/8″ to 1/4″. If your RB67 or RZ 67 is missing the 1/4″ tripod screw adapter then you might well need one of these. Several accessories like the RZ67 left hand grip, RB67 power supply for motor backs and the RZ67 power winders cannot be mounted unless you have this screw. It is missing on many cameras.
An essential item for many RB67/RZ67 users. This one comes complete with the locking screw – you won’t get that on any third party adapters. Try finding another one – these are almost impossible to find.
