Your quote has a problem. "Even" professionals don't work by themselves. First, it's not universally true. Some do work alone. Second, it implies homeowner's won't do it if professionals don't. Homeowners are HIGHLY likely to work alone, no matter who says what. So, this product WILL be used by solitary people.
I have a couple of those Guardian bucket set ups. Very nice set up for a reasonable price. Only question I have is why is this harness (as most) so hard to clip on yourself. I always have to have another person clip or unclip from the d-ring. Why can't the d-ring or the lanyard clip be long enough to clip by yourself?
How in the world am I supposed to reach that ring in the back, if I am working alone? I had to cob-job together an extension with some rope I had lying around. not good.
18” lanyards though....way too short to be reasonably located when adjusting during movement on the rope. Im 6’-3” tall and 240lbs, and that 18”is a short trip from the center of my shoulder blades and around far enough to reach. I realize that guardian wants to limit the fall distance, but 3’ lanyard would be much more versatile
These WILL be used by solitary homeowners. Some WILL fall over the edge. How does one recover from that? Have you ever seen a fifty-year-old homeowner pull off a heel hook and climb back around a leaf gutter onto a 15-year-old shingled roof which has granules that peel away during a palm smear? I would like to know how this is supposed to happen. Personally, I've used rope protection designed for rock climbing, including adding jumars for self-recovery. I don't see a self-recovery plan in the pro-in-a-bucket packages.
At that point you can have someone call the fire department or get a neighbor with a ladder. I would rather dangle off a roof for 45 min then fall 30 feet.
Put on a winter jacket, put your harness on over it, get on a scaffold plank 20 feet up, clip and unclip multiple times (as in getting on and off the roof ETC). Add up how much time you waste. I am far more athletic and flexible than average and i have a very difficult time with "this" brand. I have used several other brands and had an easier time with it. Either you are using a different style/brand or you are mistaken. The ones I have are very difficult to unhook by oneself.
