ABSTRACT:
An insert for a hold down bar which serves to hold down adjacent hatch covers of a railroad hopper car. The hold down bar includes an inverted channel, and the insert includes a rigid bar which carries a resilient gasket. The bar can be bolted in the channel with the gasket located to seal against the end of the hatch cover when the hold down bar is located down on the cover. The insert is used when an older hatch cover having a rain bar is replaced by a replacement cover that lacks a rain bar. The insert occupies half of the channel so that a second identical insert can be added if two adjacent hatch covers are replacement covers without rain bars.
