摘要：
In a railway freight car an elastomeric boot is attached to the entrance and/or exit of a hollow sill or hollow structural member through which a brake rod passes. The brake rod passes through a brake rod opening in the boot in entering and/or leaving the sill or structural member, and the boot engages the brake rod sufficiently to substantially prevent moisture from passing through the boot and into the sill or structural member.
