Semi Truck Saddle Tool Box with Two Steps, 15in Wide — Aluminum Step Box

A saddle tool box, a step tool box and a step box are one object. It fills the empty frame rail between the fuel tank and the quarter fender, with two steps at the front. Most tractors leave that space empty. This fills it and keeps the step.Ask anyone who has torn a box off a frame: bolts through the floor of a box full of chain pull through aluminum. This one is not bolted to the frame. It sits on brackets that carry the weight, and those bolt or weld to the rail. Brackets sold separately.The lid opens across the whole box rather than a narrow hatch, so a coiled chain goes in flat. A gas strut holds it up. Chains rust in an open box. This one closes onto a rubber seal running the full perimeter. It locks, and two keys come with it. Lid and both steps carry punched tread formed into the aluminum.Measure the gap between your fuel tank and the quarter fender. That picks the width, not the make. The 15in sits in the middle. If your gap takes the 18in, there is no reason to go narrower.
