Product Overview:

The DIRECT nosebox line combines all the best features of our original liftgate charging systems with a solution that saves you space on the trailer by integrating the liftgate charging system into a nosebox. There are three options available: the MAX, FLEX, and PLUS.

The DIRECT nosebox line also includes an interior light control (harness and relay sold separately) that allows the driver to select whether the lights remain on for 30, 60, or 90 minutes. This lets the driver work as needed inside the trailer while ensuring that the batteries will not become depleted by the interior lights.

Maximizes battery life and allows the liftgate to work more efficiently. X X X
Features an easy-to-read LED display that clearly shows the status of the charging source and the liftgate batteries, helping drivers and technicians quickly determine any problems with batteries or power path. X X X
