Trublue outdoor use

Thoughts on outdoor use?

Is it reasonable to expect to rap into anchors with this device, set up and use?

If 70’ to the ground I would think you could use extension on the 61’ line. Agreed? Concerns? To note would anchor on sport route for extension addition

Why?  What are you trying to accomplish?

I don't really have much to add on whether this should or shouldn't be done (don't want to wade into that discussion), but definitely look into how TruBlue recommends hanging the device. In the gym, there's always a nice flat surface for the device o hang against, or it'll free hang on greater than vertical walls. Since you'll be in the outdoors, my concern would be having weird pressure points from rocks sticking out, or having dirt or gravel ingress into the device. It might be a good idea to inspect after each climber for the first dozen or so climbs. Maybe pad the back of the device?

I can imagine a scenario where a bit of rock sticking out could turn the device, causing the webbing to run against a sharp edge that you don't notice from the ground or during initial anchoring. And I wouldn't recommend extending the OEM line, for no other reason than the device probably wasn't built with additional length of line in mind, and you really don't want to find out that it locks up, or worse, drops climbers freely until hitting the OEM 61' line.

We use retractable lanyard systems all the time outdoors for tower work, but I don’t trust them because I can’t see inside to see what condition it’s in. I do trust myself not to fall and thus I am not relying on it, just for OSHA compliance. I have no experience with the TruBlue so no idea if it is made to the same standards as industrial fall protection systems. One thing to keep in mind is that a lanyard (wedding) can be cut much easier than a rope on a sharp edge. Any anchor system even a 10’ long one is only as good as the weakest part of the system. I really can’t think of a scenario where any retractable lanyard system would be better than a rope and a good TRS  (top rope solo) setup and they are way cheaper. Even if I had one given to me I wouldn’t set it up for kids, or any one that didn’t have enough climbing experience to work a TRS setup simply because you can not inspect the mechanism inside, you can pull it hard to confirm it locks and slowly pull the lanyard out to confirm it is in good condition though. Maybe if it was something that nobody would fall on short of having a heart attack I might set one up.
