Simple rope and ascend descend ability

[jdkah]

I do some work on roofs and would like a basic system to tie myself down with a rope and be able to work hands free with protection from falling. I've heard that the arrestor devices out there require a minimum of 8mm rope? I'm looking for a quick release device that allows me to feed rope and arrest it.
