An innovation to the PTFE thread market, Solar Thread, from Pennsylvania Thread Co., is a twisted thread that sews neat and clean. It is made in the U.S.A and offers the same warranty as the competition. Ideal for boat covers, awnings, tents, filtration and other outdoor sewn applications, Solar Thread maintains 100-percent of its strength after years of exposure to sun, rain, chemicals, UV radiation and salt. With the longer life expectancy of today’s fabrics, fabricators must use thread that lasts longer. New customers get a fourth spool free after placing an order for three or more spools at regular price.
