safety gear suggestion needed please

[bradleyheathhays]

Hey everybody. I'm not exactly a climber but I figured here was the best place to consult for advice. I'm about to do some work on a somewhat inclined roof on a 1 story structure and I'm designing the gear to keep me safe. This setup is only designed to keep the rope attached to me in case I start to slide and need to get stopped. There's really no possibility of getting into a freefall with my situation. Here's the harness and rope I got...





The rope is just over 1/2 inch at 9/16 ths and looks more like boat rope. Anyhow, the last piece I need is the attachment point between the rope and harness. Not familiar with what it would be called but I've seen it as a metal piece that the rope loops through whereby the rope can be loosened and pulled through when I need to adjust.

Can anyone possibly give a picture and name of the piece I'm looking for keeping the rope size in mind?. Also, where would be a be a good place to get such a piece at a reasonable price?

PS sorry about the pics don't know why they're all woppyjawed

Thanks for the help

Yeah I hear ya. Need a better rope for sure.

I'll probably be going with a prusik knot and locking carabiner option. Been told to look for 5-7mm supply rope to make the knot out of. What search terms should I use on ebay to find the right kind of rope for this? I'd rather get something meant for the job rather than boat rope again.
