Madaco Safety Roof Construction Fall Protection Heavy Duty Industrial Safety 30FT 3-Strand Polypropylene Rope Internal Shock Absorbing Pack Snap Hook Grab Kit

Luckily I didn't have to test it. It appears to be good qaulity, and easy to expand your line while working on a roof.

Robe is white I use it to take snow off my roofs so not so visible. Functions great good quality hardware but heavy. Very satisfied but I would add color on rope for Canada as it disappears in the snow and you could trip on excess rope.
