Touring - Tubus Cargo Rack: Should mounting arms allow rack to tilt back and forth?

I just attached a new tubus cargo rack and the mounting arms slide through an eyelet where they attach to the rack, allowing for an adjustable fit but also causing the rack to tilt back and forth. Is this a proper installation? I don't see a way to immobilize the arms but it just doesn't seem right.

bolt on underside of rack needs to be tightened if I'm following your description correctly.
Directly below where the bars go into the rack attachment.

You may be making the same mistake I did when I first installed my Tubus Cosmo. There are two barrels which the horizontal stays go through on the underside of the rack, right? Well, what I did was put these in backward, so that the nut on the side of the barrel could not tighten the stay. It's hard to describe, but basically look at those adjustment barrels (under the top of the rack, which the two stays go through from the seat stays). These can be mounted the right way, where tightening the nut on the side of the barrel will secure the stay, or backward, in which case no matter how you tighten the nut the stay isn't being clamped on. I only realized I had it the wrong way around when my rack suddenly swiveled backward on one of my test rides. I was embarrassed to say the least once I realized my mistake, but it's good to know someone else was taken in by this too!
The allen bolt on the top of those barrels only keeps the barrel in place side-to-side in the slot, I don't think it has anything to do with keeping the stays clamped.
Hope that helps,

i use a swivel socket wrench with 8mm and 10mm and will carry this on trips, in addition to my folding allen key set - these two are the only tools that i'd need for my tubus. i turned the "joint" so that the 8mm nut is facing the outside of the bike... easy for adjustment. i do it partly because i dont want to bend my extra long aluminum stays that i ordered previously....
Neil, it was that the mounting arms weren't on properly, not allowing me to tighten the nut! All's well and immobilized now. Thanks so much. I have to say this forum is so wonderfully helpful - thanks everyone for your input - it was all helpful!!!
