2015+ 900S and 900 4 Seater Cargo Box

I’ve googled and seen a few threads with this same question unanswered so thought I would post here. Does the 900S Rear Cargo Box still work with the rear roll cage extension bars? The 900 4 seater comes with this as standard and no way to remove them as they are not add ons like the 900S.

I was also looking at the XP1k 1/2 box as it seems a bit smaller. Wasn’t looking to take up the entire bed in the back, but love your boxes and by far look to be the best quality available.
