#SmallRig Right-Angle Adapter for BMPCC 6K Pro Cage 3289

The SmallRig Right-Angle Adapter for BMPCC 6K Pro Cage (Model 3289) is a highly specialized, structural 2-in-1 electronic routing accessory. It is engineered specifically to work alongside the SmallRig Full Cage for BMPCC 6K Pro / 6K G2 (Model 3270 / 3270B).

Because the Blackmagic Design Pocket Cinema Camera features data ports that protrude directly out of its left side wall, running standard straight-headed cables can make your camera rig awkwardly wide. The 3289 adapter solves this by physically redirecting your primary monitor and storage data links by 90 degrees, routing them cleanly toward the back of the camera alongside the tilting LCD screen.

Key Engineering and Structural Features

• Dual Interface 2-in-1 Molded Block: The adapter houses two independent data pathways in a single solid PVC casing: a Full-Sized HDMI female-to-male terminal and a high-speed USB Type-C female-to-male connection. Both connectors line up perfectly with the native port spacing of the camera's input panel.

• Anti-Shedding Thumbscrew Lock: Unlike loose consumer right-angle adapters that can easily wiggle out of their sockets under friction, the 3289 features an integrated stainless steel thumbscrew. The screw runs through the plastic housing and anchors directly into a dedicated M4 threaded hole on the left side wall of the SmallRig 3270 cage, locking the connection firmly in place.

• Zero Impedance Multi-Protocol Transfer: The internal wiring traces are engineered to protect structural data transfer rates. The USB-C line fully supports the high-bandwidth requirements needed to record uncompressed 6K Blackmagic RAW data streams directly onto an external Samsung T5/T7 SSD without data dropouts or frame skipping, while the HDMI bridge handles pristine 1080p and 4K video monitor feeds.

• Streamlined Space-Saving Footprint: By flipping the cable direction backwards, the adapter drastically reduces the risk of snagging cables on door frames or branches when executing active handheld tracking shots. It also frees up space on the left side of the cage, making it easier to attach side follow-focus motors or wireless audio receivers.

💡 Operational Rigging Tips for the 3289 Adapter

The Environmental Operation Restriction: According to SmallRig's strict manufacturing testing notes, you must not utilize the 3289 adapter in damp or humid weather environments. Because it is a rigid, multi-port block that bridges the camera's interior digital pins, it lacks the weatherproof rubber sealing gaskets found on standard premium cable heads. Operating it in light rain or dense mist can trap moisture inside the side panel cavity, risking an electrical short across the camera's native logic board inputs.

• Executing the Balanced Alignment Protocol: When installing the adapter, do not drive the side locking thumbscrew all the way home immediately. First, gently slide the male HDMI and USB-C connectors straight into the camera bodies until they sit fully flush inside the sockets. Once the data pins have safely found their home position, take the included Allen wrench and gently tighten down the side anchoring thumbscrew against the cage wall. This stepped sequence prevents the metal screws from forcing the adapter in at an angle, protecting the delicate internal pins from bending.

• Combining with the 3271 Cable Clamp for Maximum Safety: For absolute data protection on heavy production sets, mount the SmallRig HDMI & USB-C Cable Clamp (3271) onto the rear section of your cage right behind where the cables exit this adapter block. Because the 3289 adapter redirects your cables to face toward the back of the camera, locking the trailing cable lines down into a mechanical clamp ensures that any sudden, accidental tugs pull against the aluminum frame of the cage rather than snapping the adapter's internal connection.
