A pair of replacement set screws for CycleTote Bicycle Trailers.
These screw hold the tow bar or the jogger and stroller wheels to the trailer. With their winged tops, you can easily unscrew the tow bar and separate it from the trailer.
First, disconnect the tow bar from the hitch, then turn the red set screw until the ends disappear into the trailer's frame. Now slide the tow bar up and out. This lets you condense the size of the trailer for storage or travel. Or slide in your wheel for the jogger or stroller.
