The McWelco DX series under bed truck box features an internal rain gutter built into the header and door jambs which eliminates the need of a sealer except at the bottom of the door. This allows the box to breath which eliminates condensation problems. The header and jamb design also forms a very ridged section which greatly helps resist damage from abuse and/or attempted forced entry. The door which is constructed of Heavy 12 ga. steel is supported by two "tailgate" type arms that will support a working load of 250 lbs. and can be used as a step. The door can also be released to swing straight down. With the body made of 16 ga. and the door of 12 ga the weight is distributed to the areas most needed while the over all weight is held at a sensible figure so as to retain the greatest useful load capacity for your vehicle. McWelco's DX series are simply the finest under bed boxes available.
