I am looking for a replacement roof canopy for my canopy, a 10 ft. x 20
ft. steel frame canopy, P/N 680344 from Costco. The P/N is 2004-D,
14'4"/4.3m x 22'5"/6.8m Polyethylene canopy roof. The manual has a
customer service number of 1-800-929-9517, but when I call it, I get an
ad, or service not available message. Anyone have any luck getting a
replacement roof for this popular canopy ?
