Abstract: A storage compartment for truck tractor lines closed, when installed, on all sides except for that portion of a shelf necessary to admit and hold the glad hands and power plug. An optional lower cover can close the entire container when no glad hand or power plug is present. Access is through a rear door which can preferably be placed and remain in either an open or a closed position. Optionally, at least one projection is attached to the front of the container to hold extra rubber grommets for the glad hand; and at least one spring is similarly attached for releasably retaining a flashlight, pressure gauge, or other items of use to a truck driver, such as an air line repair kit.
