发明名称 Rodent barrier for door over railroad track
摘要 A rodent barrier system adapted for use with respect to a vertically closing door in a warehouse or other storage facility wherein the door moves downwardly to a closed position over a railroad track. The door rodent barrier includes channel members mounted on the inside of the rails of the railroad track, each channel member having a groove therein for receiving a detent portion of a complementary configuration, such detent portion being part of a barrier plate mounted onto the vertically closing door. In the closed position, the detent portions of the barrier plates are nested into the channels in the channel members thereby preventing the passage of rodents between the rails of the railroad track and the closed door.
