Robline Sirius 500 is a polyester halyard with a 32-plait polyester cover and 8-plait core, which runs easily through blocks and tackles. A popular line for standard halyards.
The line is UV-resistant, easy to splice, and easy to handle. It grips well in cam cleats and clutches and is well-suited for rig setups where low stretch and high abrasion resistance are important.
