K'NEX Chain-Guide Clip

These chain guide clips create a "trough" for the chain to slide through for the SS K'nex roller coaster models. Whether you want to create a cleaner looking lift hill or want to hold the chain tight to the track for an inverted roller coaster model, this may be a solution for you.
The additional items you will need are #4-40 screws* (around 3/8" in length) to connect each of the clips to the K'nex track pieces (as show in the above pictures) as well as the original K'nex roller coaster track rails (orange plastic rails) to run the length of the lift hill on both sides of the clip.
