I had my fingers crossed that my Partner compact fire pan with the lag bolt legs would pass inspection on the Grand Canyon. My friends realized at the last minute that none of their fire pans had legs and borrowed mine. I've heard that the GC rangers are pretty picky about gear, and I didn't want my friends to be stranded without a fire pan. It passed, and I breathed a sign of relief. My fire blanket is 4ft. X 4 ft., so it wouldn't have passed. GC requires a larger fire blanket, 5 X 6 I think? They had a large welding blanket, so they were good.
Awhile back there was a post about a take-apart fire pan that was used by a kayak self support group. Light weight and pieces could be spread out between multiple people. It looked really cool, but when I priced out the parts to make one, the Partner fire pan was a bit cheaper. 15 X 13.5 X 3.25 and 15 lb. isn't too bad to pack on a raft.

If you're handy with metal work this is a really cool design.
