Railcar Stoppers

Bring slow-moving railcars to a halt. These stoppers have a chock at the end of a handle that you can place and remove in front of a wheel several times to absorb its momentum. They can hold a wheel in place until you install a permanent chock. After you’ve positioned a car with a railcar mover, they’re great for stopping it at an exact location. Use them to guide railcars to scale checks, repair shops, and loading zones. These stoppers are for use on flat track only.

DIN Rail Stops


Screw On Rail Stops for DIN 3 Rails	Snap On Rail Stops for DIN 3 Rails	Screw On Rail Stops for DIN 1 or DIN 3 Rails	Screw On Rail Stops for DIN 2 Rails	Screw On Rail Stops for DIN 1 Rails

Stop terminal blocks, relays, and other components from sliding along DIN rails.

Screw On—As you tighten the screw, these stops wedge into place on the DIN rail for a more secure hold than snap-on stops.

Snap On—Press these stops against a DIN rail and they snap into place. Since you don’t need tools, they’re faster to install or remove than screw-on stops.

For DIN Rail Trade Size—We gave each type of rail a trade size to help you quickly find compatible parts. DIN 3 is the most common type of rail—it's also called top hat or standard rail. DIN 2 is a smaller version of DIN 3, so it's also known as mini rail. DIN 1 is also known as G-section rail.

Group Markers—Label these markers and attach them to stops for easy identification.

Railcar Wheel Stops


Foldable Wheel Stop Shown on Rail	Wheel Stop Shown on Rail (Sold in Pairs)

Stop moving railcars at track ends and as they approach buildings and doors.

Foldable—Foldable wheel stops swing down to the outside of the rail when not in use. You’ll need a left and right stop for a complete pair. They come with a padlock to keep them in the upright or lowered position, preventing unauthorized use. Bolt these stops onto your rail after drilling four 1 _1/16″ holes into the rail web.

Not Foldable—Nonfoldable wheel stops clamp to a rail, so no drilling is required for installation.
