STEIN Skyline throw-line is manufactured from UHMwPE which stands for Ultra-High Molecular Weight Polyethylene otherwise known as Dyneema.
Available in three different sizes ranging from 1.5mm to 2.2mm with average breaking strengths ranging from 250kg to 450kg (1.5mm = 250kg | 1.8mm = 350kg | 2.2mm = 450kg).
This line has an 8-strand flat construction which allows it to store neatly and when deployed reduces the nesting issues associated with inferior lines.
