To ensure a safe delivery of an Office Trailer from Eagle Leasing, there are a few key requirements. First, you will need a 2 5/16 ball hitch lock to securely attach the trailer. Additionally, it is essential to have a breakaway box installed, which serves as a protective measure during transportation. The breakaway box includes a chain and a box that secures the ball hitch area. This precaution becomes crucial in case the trailer encounters a pothole while on the road, as it helps prevent the trailer from dislodging off the ball hitch and potentially causing an accident.
