Cortland Spectra® 12 Strand and 12×12

Spectra® 12 strand provides very high strength, low stretch and excellent abrasion resistance in a single braid construction.

The equivalent weight rope is more than 3 times as strong as polyester and has less than one half of the elongation.
Spectra® 12 strand is delivered standard with a polyurethane finish and is easily spliced using a simple lockstitch type splice, 4-3-2 or 5-4-3 Tuck Splice. It’s soft, torque free braided construction provides easy handling.
