TBS Alcohol/Meths Burner Cross Members
They simply fit on the top of a burner unit to make it into an instant, very handy cooker.
Wow what a great little burner. Just like the old style Trangia ones. The crossmembers are great precision cut pieces held together for travel by a small steel locking cord. The burner along with cross members fit perfectly into my Pathfinder cookset windshield, bonus,allowing me to add another fuel option to use with it. The burner is well made and does the job intended. Fantastic!
