The Cage for Sony a7S III/a7 IV with Top Handle Pro combines a formfitting protective cage with an adjustable top handle that offers side-to-side and front-to-back balance adjustments.

This provides a solid connection between the handle and cage and allows you to adjust the balance side to side, as well as slide the handle off when not using it. The top handle grip is a shaft that you can easily slide forward and back as well as remove and reverse from the NATO rail mount. This allows you to adjust the balance of your camera when carrying by the top handle front and back. The top handle grip has cold shoes on top as well as the front, and the back of the grip has an opening for a 15mm rod. The top handle grip is also replete with 1/4"-20 and 3/8"-16 threaded mounting holes.
