How could this happen? And how much to fix? Torn out glad hands

Id say youre looking at about 500 to do it right... IF the airline valve is not damaged AND you can get remains of the airline fittings out of the valve.

12' to 15' Tectran 3 way airline/electrical pigtail in coiled line guard.

1 or 2 pigtail retractor springs.

1 or 2 3-way pigtail clamps

Set of gladhand handles

 

It’s clear you hung up light cord I suspect they didn’t wrap your airlines to the light cord far enough.. once one gladhand unhooked it eventually fell into the wrong spot ripping everything apart. On your replacement set make sure it’s wrapped or zip tied together leaving maybe 18 inches unwrapped. This way if one falls it can’t be sucked into moving parts.

 

One thing for sure, the fun stopped there,,,
