What rope to use for 14.2 Harken furler?

Hello, I just order a furling jib and accessories from Catalina Direct. They don't carry the line needed for the furler. I ordered a Harken furler. I was told to purchase 30ft of 5/32 dia. double braided dacron. I can't find it online. Does anyone know where I can find it? Also, any tips for installing or using the furling jib would be appreciated. Thanks.
