There are two main types of barrier fasteners: connecting pins and anchor pins.

• Connecting pins can also be called connection pins, connection bolts, or connection rods, depending on the state. Connecting pins connect two barriers by sliding into loops on the ends of each barrier to prevent them from pulling apart.
• Anchor pins can also be called stabilization pins or anchor bolts, depending on the state. Anchor pins go through a hole in the base of the barrier and into the ground to prevent them from moving.
