Gore Tenara Thread M1003-MTR-L-5, in 1850 Denier Clear on an 8-oz spool, delivers clear PTFE thread that blends seamlessly into fabrics for marine thread and outdoor thread projects like awning thread or boat cover thread. This UV resistant thread and UV stable thread, made as three ply thread with fluoropolymer construction, provides high strength thread as industrial sewing thread and weatherproof thread that resists fading in direct sun exposure longer than typical bonded polyester thread. Unlike ordinary options, its denier 1850 thread construction holds up through abrasion and cleaning, keeping seams invisible on Tenara sewing thread upgrades for patio enclosures and cushions.
