positions only.Press the lever down and align the crossrails on both
sides with the holes on the siderails. Move the crossrail
by hand. There will be a notable click as the pins align
into the holes locking the crossrail into place.
Make sure the lever is in the down position, and that the
crossrail cannot be moved by hand when it is in place.
