SPP-130-F Switch Point Protector
Nolan's SPP-130 installed on track with shim beneath
BROCHURESwitch Point Protectors: SPP

Nolan’s switch-point protectors increase the service life of switch points by absorbing the impact of passing railcar wheels. Designed to bolt securely to the inside straight main rail that leads to  the switch, the protector momentarily deflects the wheel flange so it misses the tip of the switch point. Made from manganese steel, the switch-point protector actually gets stronger with each deflection. Nolan's SPP is reversible -- when worn down on one side, it can be flipped around and remounted, doubling its service life. SPP set includes manganese steel face plate and steel shim, steel back-up plate, two track bolts, two nuts and two spring washers.

RECOMMENDED: The mounting position of any switch-point protector may vary according to speed and traffic conditions on the track. We recommend reviewing the installation instructions that accompany each switch point protector.
