My costly experience, a Screw-gate cradle clamp on a gimbal is a pending destroyer of your camera- telephoto rig. Besides they're too slow in use. Been there once and lost a D500, which slipped out of the foot plate on a 300 f2.8G....
The only remedy is to
mix and patch components, which can require machining and altering to fit parts together. I bought the
RRS PG-CC cradle plate (discontinued) for the Leofoto PG1. However its Lever Clamp cannot adjust the throw (ie tolerance) of the locking plate; unless it's disassembled to insert shimming washers inside the lever shaft recess to adjust the QR lever throw. (Different makes of A-S foot plates differ in width, because Arca-Swiss is not a strict standard.)
It's frustrating there's little effort by the prominent Gimbal brands to design Arca-Swiss compatible Cradle arms with an adjustable locking throw on the QR lever. Looking at you - Jobo, Leofoto in particular.
Leofoto already has a 70mm Lever Clamp. UThey could offer this QR mechanism as an option in cradle arm of their
PG series gimbals; the PG-2S weighs 0.85kg only.
