Product Description

Upgrade your Manfrotto 405 Geared Head with the Hejnar Photo M405 conversion plate. This adapter provides a rock-solid foundation that allows you to mount any standard Arca-type clamp to your geared head. To use this system with your camera gear, a separate Arca-style clamp is required (sold separately).

The M405 is engineered for versatility; the eight 10-32 tapped holes allow you to position your chosen clamp in relation to the adapter plate in 90-degree increments. This ensures that whether you are shooting architectural panoramas or macro stacks, your clamp orientation is perfectly matched to your workflow.

Installation is straightforward and secure. The adapter plate attaches to the geared head in two steps: first, remove the factory lockdown lever using the provided 3mm hex wrench; second, connect the MM405 plate to the geared head using the provided 1/4-20 and 10-32 screws. The precision CNC machining ensures an anti-twist, zero-play interface that meets the high standards of geared head users.
