What the thread found

• Slippage is typically caused by inadequate shimming between ARRI grip diameter and 19 mm clamp, or between 19 mm and 15 mm interfaces.
• Operators report better results by using improved shims or removing the 15 mm bushing entirely and mounting directly to a 19 mm rod.
• A small ball-jointed arm (Noga type) placed between the monitor bracket and the SmallHD 503 can reduce binding and instability.
• Cables need not be disconnected during docking, though the overall setup remains somewhat cumbersome.
• Post extensions or the ARRI Superpost provide longer reach and greater flexibility than custom clamp arrangements.
• A third arm or reach system (Flowcine xREACH) offers ground access without relying on monitor-and-grip fixtures.
• Community interest exists in direct mounting points on the Trinity Master Grip MG2 to allow modular attachment of monitor and grips.

Depends on

• Slippage severity depends on cable routing, payload mass, and clamp tightness.
• Custom rigging versus post-extension choice depends on workflow and rig footprint constraints.
