165cm (~65") square Thule load bars with Thule #415 rail foot kit (4 roof rail clamps plus optional locks so bars cannot be removed).
The clamps bolted right onto the existing roof rails of our 2002 Odyssey, undoubtedly will fit the roof rails of plenty of other cars/vans/SUVs (see pictures for a look at the clamping mechanism).
All parts have been mainly sitting in my garage since we bought them, I only used them occasionally to haul things like sheets of plywood.
