Guardian 42003 Velocity Cable.

The new Velocity 50' SRL series from Guardian Fall Protection includes models with lengths ranging from 10' - 100', and is manufactured with heavy-duty galvanized cable. Velocity SRLs feature swivel tops and swivel snap hooks, as well as lightweight and durable glass-filled nylon housing.

I have several of these in different sizes. All work perfectly. Also have roof anchors. I will sell the whole lot at a deal if anyone is interested in more than one.
