How do I install Anti-Roll Pegs on my Vernier Dynamics Cart?

Certain dynamics cart products include a packet of Anti-Roll Pegs. The peg prevents a cart from rolling when the cart is placed on a flat surface. For example, a cart placed on a lab table cannot roll and fall to the floor. However, the peg will move in the center groove of a Vernier track without touching, and the cart will freely roll.

The peg is compatible with all Vernier dynamics carts, both our older green, metal carts and our newer plastic carts. It is compatible with most Vernier Fan Carts. Some fan carts lack the necessary end cap mounting hole, and will require replacement of the end cap. Contact us if you need a replacement end cap.

Locate the hole in the cart end cap on the underside, along the centerline of the cart. Insert the shorter, wider end of the peg into the hole, and seat it firmly with a twist. The peg can be removed in the same manner if the cart is to be used on a surface that lacks the center slot.
