: I bought another HDMI adapter from SmallRig - same problem. That's when I realized that on the side of the 2203B cage, the 2 threaded holes at the top are closer together than the 3 at the bottom (I don't mean the gap between the 2 sets - they're literally closer together). The original 2203 has 5 equally spaced threaded holes. So while you can't mount it according to the photos showing the updated cage, you can mount the device in the bottom three holes and still have access to both ports. Looking at photos of the original 2203 cage I think it will work as intended here. ORIGINAL REVIEW: Purchased as a pair with a regular Smallrig 2203B cage for Blackmagic Pocket 4K/6K. It's like nobody actually installed it on the cage after it was made. It's literally incompatible. No matter how much lateral force I applied, I couldn't get the screws to look straight. I thought it was because of that little metal plate that acts like a washer under the screws. I tried attaching it to the cage thinking that pulling on the screws would help. nope In fact, just as it appeared to be flush, it began stripping the threads of the mounting hole. on my new cage. I ended up pulling out the screws and putting them directly into the designated spots on the cage. The heads are literally too big to use in adjacent threaded holes! See photo - screws overlap and can never sit next to each other. If you have a BMPCC 4K/6K cage - no worries! Also, I tried a screw for fun, and when I plugged this device in, the cables were so stiff that they seemed to exert lateral pressure and push against the connectors, defeating the purpose of this device. I love SmallRig products and have been using them for over 10 years. but that's nonsense. Don't waste your time.
