The F4 Skate Retarder is unique among competing skate retarders in that it adjusts its breaking force, according to the car’s weight, virtually eliminating wheel pop-outs and increasing the lifespan of the retarder’s friction components. The F4 skate retarder is assembled and panelized for easy installation.

Panelized as a three lever section F4 with a transition section, followed by a seven lever section, the F4 Skate Retarder provides more holding power by grabbing on both sets of rail car trucks. This creates a higher dynamic force and also reduces consecutive impact rail car run outs.

The F4 features easily accessible components combined with a simple gauging process. The result is a simple product to maintain in the field.
