Thule knows racks like a strip club bouncer. The Snowcat is pretty much perfect for mounting on most factory roof rails that are the front-to-rear variety (not the left-to-right). It installs quickly and with no additional hardware required. Just telescope out to the necessary width and lock them down. Stick three pairs of mid-fats or a snowboard on each side and you're good to go.
The best thing about the Snowcat is that it comes with integrated locks. No more buying little lock cores as add-ons. The locks are intelligently designed so that they cover both the mounting hardware and the big old button that releases the scissor-style clamps that hold the skis down. Those add-ons can cost a pretty penny, and the Snowcat does it all for a very reasonable price.
