I work as as AV professional and have never seen that exact 90 degree configuration. You can easily do it with two adaptors however - RCA F to M 90 and then a straight F BNC to M RCA. The depth (at the 90) would be the same, just a bit longer in length. Or, you could reterminate the cable end to an RCA.
Need Female BNC to Male RCA 90 degree adaptor...?
Hey guys, I have a digital cable termed with male BNCs. I'm needing an adaptor, female BNC to male RCA, 90 degrees, for an incredibly tight squeeze. Unless, I'm missing something I can't seem to find the trick. Anyone have any suggestions? Cutting away at the back of the cabinet is not an option.
