One of the innovative features of the Quik Rack Mach2 is the captive safety pin at the hitch (shown with the red knob in the photo below).
The captive safety pin serves as a fail safe if the rack were to become loosened and start slipping out of the receiver. The rack will only become loose if it isn’t tightened properly with the blue lever and periodically checked.
The captive safety pin was designed because, for whatever reason, there is no standard when it comes to hitch receivers and their hitch pin holes. We cannot rely on you being able to use a standard hitch pin so the captive safety pin solves this issue for most vehicles.
The captive safety pin can be removed entirely (though we don’t recommend it) and it can easily be switched to the opposite side. This is necessary with some vehicles due to space restraints and electrical connections in the area of the receiver.
