For Sale is a Tarp Door Kit from Warbonnet. Stuff sack is included. I bought it used to try out with my BMJ tarp and only set it up once. Don't really need it here in southern CA.
Warbonnet says it will work with BMJ and Cloudburst tarps. Not the Edge Tarp. They are brown silnylon.
$50 (includes shipping in CONUS) via PayPal and it's yours.
