I do not, sorry. I purchased it from my local hardware store. it is 4' wide and comes in a roll of 100' but they cut the length you want. I believe it is vinyl table cloth and was about $2/foot.
After 2 winters I finished my covered and secure run; part of an attached pole shed with metal roof and HC everywhere. Being secure I get to leave the pop door open.
1st winter I used HD grey tarps on the walls to provide shelter, this past year I used clear vinyl.
Open access to both run...
