CAMVATE Universal Camera Cage with Top Handle and Wooden Handgrip

The top handle comes with a single rod clamp and a hot cold shoe mount, which allows extending and DIY. It also provides plenty of 1/4"-20 and 3/8"-16 threaded holes. The side cheese rod is 197mm long to fit a DSLR camera with removable battery grip. You could alter the top plate and baseplate to the opposite side to avoid blocking the trigger as you need.
