VEVOR Steel Core flipline, 1/2" x 8' Arborist Flipline, Flip Line for Tree Climbing with Alloy Steel Snap Hook, Aluminum Alloy Carabiner and Extra Tool Lanyard, for Arborist, Tree Climbers

There was not any certification information. If you plan to use this for personal use I don't see any issues, but if you want to use it professionally for co-workers, I suggest a ASME certified lanyard. In Canada all safety lanyards are required to have an annual safety inspection. For personal use it is no better or worse than any other lanyard I've used, but without actual certication I can't allow anyone else to use it. Hope that helps.

No it does not have any certifications regarding safety.

YES

I don’t think so. The end of the flip line has a loop crimped on there. I’m pretty sure the loop doesn’t fit through the rope grab. I don’t have it in front of me.

Haven’t taken mine off yet but it should be removable. There’s a bolt with a lock nut running through it.
