ok so we used the key and unlocked the rails. slid them to the middle where it looks like you should just remove them and they will not come off, am I missing something?

 

Did you loosen the allen bolts? Also, there are a few spots they can come out, if I remember correctly, but they are a pretty tight fit. The bars have to be completely perpendicular to the rails or they will bind trying to remove them. They CERTAINLY aren't as quick on and off as the D1 or D2 bars.

 

allen bolts? I assumed you just unlocked them and slid to the large open spot in the track and lift them out, guess I will look for the allen bolts

 

It just loosens up the feet so that the can move in and out a little on the bars.

I figured it thanks, just unlock the ends and slide off that top little plastic plate, the Allen screw is there, loosen just 1 per bar, slide them to the middle and lift off
