I'm a big fan of multiple sources as I've tied knots incorrectly before. So far I haven't found any sequence of pictures showing how to lock off a dual hyperbar microrack but I have found a Youtube video by Derek Bristol: (around 5:14) https://www.youtube.com/watch?v=msl10WG ... rekBristol

Any other sources I can look to just to make sure I'm locking off correctly?

I would lock a dual hyperbar minirack exactly the same way I lock a single hyperbar minirack. That is - One wrap over the upper hyperbar, stuff a loop through the frame, give it a half-twist and hang it on the upper hyperbar. Derek's video demonstrates this method.
