What the thread found

• The screw on the Arri 435 lowmode unit can interfere with DB III mounting because the DB III is wider than the lowmode unit
• Removing the screw entirely is a temporary solution that works but may void equipment insurance and is not recommended for extended use
• A spacer plate approximately 1/4 inch thick made from aluminum can be added under the camera to clear the screw head
• An alternative bracket designed for the 435 lowmode can bypass the standard Arri bracket and eliminate the screw interference issue
• Anti-slip rubber or camera tape added to the DB III clamp can improve grip and reduce slipping under load

Depends on

• Removing the screw is described as a temporary measure only, not suitable for long-term use
• Some rental facilities may void insurance coverage if the screw is removed
• The effectiveness of anti-slip modifications depends on the individual DB III unit, with some slipping more easily than others
• One user tested the anti-slip rubber modification only on a light camera setup and expressed desire to test with heavier configurations
