The new E-Line Model 143 is the first truck saddle box to offer Weather Guard quality at a lower cost, says manufacturer Knaack L.L.C. With a tamper-resistant, piano-style hinge providing security, the saddle box has a reinforced aluminum diamond-plate body with an automotive-grade, baked-on, powder coat. Automotive-style latches with a paddle handle mechanism allow for single-handed opening, even with bulky work gloves. When fully open, the box cover sits at a 90-degree angle.
