Those reels are very nice and give the worker plenty of mobility. However,
I understand they are more costly than a simple sewn fall arrest lanyard,
and I don't see the need for one in my tower work.

I am fascinated by the description of the fall-arrest device using a reel
similar to those used on auto safety belts. I have checked the Pinkerton
Sales and Ultra-Safe web sites, but have not seen anything like this. Did
anyone get a part number or other identifying info?
