Very nice Aero Specialty tow bars and heads for CRJ series aircraft or Challenger 300/350 or 850 private jets. These are heavy duty tow bars for serious use. I have a number of them. Some are lightly used and some are a bit older style with more use. Price depends on which ones, but happy to make a good deal!
New, these are $5000.00+ from Aero Specialties. I've got them for a deal!
