To provide a better grip to the tracks, tighten the screws of the toggle bolt. Next, pull the wires through the end of the track and attach it to the screw terminals. To conceal the wiring, install a cover plate at the end of the track. Lastly, mount the light fixtures by pushing the top of the fixture into the track, aligning the contact blades parallel to it, and rotating its base by 90 degrees to lock it in place.
