4-4 Storage Midgate Drain Grate Removal and Cleaning 2. Do not force the grate. If it does not clip into place, realign the clips with the holes and try again. Side Rail Channels The side rail channels are located on top of both sides of the cargo area. Flush them out with clean water if debris collects inside of them. Carefully load cargo into the cargo area, so that the rails do not get damaged. The removable Midgate drain grate is located near the base of the Midgate. After hauling dirt, wood chips, pebbles etc. the Midgate drain should be flushed with water. First remove the drain grate: 1. Lower the Midgate. See Midgate® on page 2‑8 for more information. 2. Pull up on the rear side of the drain grate, tilt it toward the front of the vehicle, and pull it out. Reverse the procedure to reinstall the drain grate.
