Pro Arm and D-Box 2 operation, canister adjustment, and socket block swapping procedures
18 years old. Gear and prices may have changed since.
What the thread found
- The Pro Arm uses a 5/32 inch T-handle wrench for all adjustments including spring tension and canister removal via the drawbar retaining screw.
- A combination of one black and one blue canister per arm section covers approximately eighty percent of typical camera weight ranges.
- Black canisters should be positioned on top in the forearm and on the bottom in the upper arm for easier right-handed access and maximum tension adjustment range.
- Canisters do not require pre-tensioning before installation; they can be adjusted in place after insertion into the chassis.
- Socket block swapping involves using two golden spanner wrenches to unscrew the caps on the vertical axle pin at the vertical link, removing the axle pin, flipping the socket block adapter, and reinstalling the axle with its cap.
- The six caps on the socket block require periodic tightening, especially during vehicle-mounted shots.
- D-Box 2 models have adjustment knobs only on the dummy side and lack coarse adjustment capability.
- D-Box 2 quick release levers still require 5/32 inch wrench tightening.
- Pro 2 gyro mounting options include battery rack mounts, Anton Bauer plate mounts, camera plate mounts, and post clamp mounts.
- Inverters can be mounted between Anton Bauer plates or secured to the rear of the Pro vest using Velcro patches with wired AB plates.
Depends on
- Advice applies to Pro 2 rental rigs; some user manuals may not be provided with rental units.
- Canister configuration assumes typical camera weights in the stated range; heavier or lighter setups may require different combinations.
- Socket block adjustment caps need checking periodically but specific intervals are not defined.
- Information is based on experience with specific steadicam equipment generations.
