Yes, Grim, it's the 15 x 8 x 11 1/2 size.

Glad someone else has tried this. It's not stealing, it's sharing.
I use their other boxes as rack trunks for most of my daily commutes and secure them with a simple bungee.
I highly recommend the MEC pannier clips for security and bungee-free simplicity.
Great pics. One of these days I'll get pics of mine posted...
Best wishes.
P.S. By the way, the cheapest place I've found these boxes is at Northern Tool online. They now carry the orange as well as the olive in small and medium.
