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

Screw On—Screw-on stops wedge in place against the DIN rail as you tighten the screw for a more secure hold than snap-on stops.

Snap On—Snap-on stops clip onto the DIN rail with no special tools required, so they’re quicker to install and remove than screw-on stops.

DIN Rail Group Markers—DIN rail group markers mount onto stops—label them 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.

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.

Support-Rail Two-Piece Shaft Collars

Snap onto a support-rail shaft to create an end stop for carriages, bearings, and other sliding components. These two-piece collars attach anywhere along the shaft when other components are already installed or you can't access the ends. They clamp firmly and evenly without marring the shaft, so you can reposition or remove collars later.

Black-Oxide Carbon Steel—Dark and matted for a finished look, but with minimal corrosion resistance. Best for dry environments.

Support-Rail Shaft Collars

Create an end stop for carriages, bearings, and other sliding components. Push these collars over the end of your support-rail shaft and tighten with the clamping screw. They grip firmly and evenly without marring the shaft, so you can reposition or remove them later.

Black-Oxide Carbon Steel—Dark and matted for a finished look, but with minimal corrosion resistance. Best for dry environments.

303 Stainless Steel—Withstand moisture and mild cleaning solutions, such as acetone and ammonia. These are easier to machine than other stainless steel collars.

Magnetic Railcar Wheel Chocks

To firmly hold railcar wheels in place, these chocks have magnets on the back for extra grip on rail tracks. Use them to keep railcar wheels stationary during loading, unloading, and servicing.

Railcar Wheel Chocks


Single Chock	Single Chock with Red/White Flag

Double Chock	Double Chock with Red/White Flag


Exposed Rail	Paved Rail

Chock the wheels on stationary railcars to keep them from moving during loading, unloading, and servicing. They’re for chocking railcars on a flat track, so they’re not recommended for use on tracks at an incline or decline. Chocks install quickly, without tools.

Single Chock—Single chocks prevent forward motion.

Double Chock—Double chocks prevent forward and backward motion.

Railcar Wheel Chocks with Red/White Flag—A flag indicates that chocks are in use.

Painted Steel—Painted steel chocks are connected by a chain; a rubber strap attaches to the chain and draws the chocks together.

Polyurethane Plastic—Polyurethane chocks won't degrade from corrosive chemicals, unlike steel chocks. They’re compressible, so they can expand back to their original shape. As a result, these chocks will not cause a spark or damage to the rail if a railcar runs them over. When you’re ready to remove them, pull the railcar over them before retrieving. They're connected by a cable, which weighs less than a chain and won't corrode from moisture.
