Product Description

Upgrade your Manfrotto 405 geared head with this professional Arca-Swiss conversion set. This system allows you to bypass proprietary Manfrotto plates and use any Arca-style quick release equipment. It is the ideal solution for architectural and interior photographers who rely on the fine-tuned adjustments of a geared head but require the speed and modularity of the Arca-Swiss standard.

The included F63 clamp features a sophisticated "tongue-in-pocket" design. This keeps the jaws perfectly aligned, eliminates unwanted bending forces on the threaded stud, and protects internal components from field grit. For maximum flexibility, the clamp can be positioned in 90° increments on the plate or removed entirely for use on other gear.

Installation is simple and non-destructive: use the included 3mm hex key to remove the factory lock-down lever, then attach the Hejnar plate using the provided 1/4-20 and 10-32 screws. The result is a rock-solid, low-profile interface that preserves the accuracy of your 405 head while expanding your mounting options.

*Note: Custom knob options (long black, short black, or short silver) are available upon request in the checkout comments.*
