Had a 24 in X 24 in X 80 in cage put on over the winter by a local welding shop (fabricated by them) and it cost $400. I looked at buying off the shelf ones and by the time you buy, ship, and get installed it would have been that much or more.I want to add a lockable cage to the front of my trailer. Does anyone know where I could get this done. I'm in Charlotte, NC. How much would this cost? Thanks!!
