ABSTRACT:
A railroad crossing gate flasher assembly has a sealed, rodent-proof connection for electrical cables that pass from the foundation to a junction box. A clearance between the bottom of the junction box and the top of the foundation is sealed with a plate to prevent rodents from accessing the cables. The seal plate is mounted to the bolts that extend from the foundation and is leveled after it is inserted onto the bolts. The junction box is lowered onto the seal plate and attached to the same bolts so that the junction box also is level. The seal plate has an opening, coupling and conduit for protecting the cables.
