HARKEN Light-Duty #2721 Track End Stops (Pair), 174

CB (Captive Ball) high-beam variable hole spacing track is used to span cockpits or other unsupported areas. The track features internal slide bolts, allowing a new track to be installed without drilling additional holes. When control blocks are not used, add endstops to the traveler track to absorb shock loads, and keep the car on the track. When end control blocks are used, use trim caps to finish track ends.
