Product Description:
Low Profile Replacement foot for: Canon 400mm F/4.0 DO IS 2

Double-dovetail design allows for dual clamping surfaces on rail

To remove the Canon foot, use the M3 hex key tool that comes with the H133 to completely remove the four Canon mounting screws.

To install the H133, use the four original Canon screws and secure the foot to the lens collar.

If your mounting screws loosen over time, consider using Loctite 242 for security.

Foot leaves enough room for your fingers under the lens to freely use the lens focusing ring.
