Install second set of RailGrab towers and crossbar.
Now simply follow the instructions from the beginning to install
your second set of towers. Be sure to read all cautions and
warning on the next page. Return integrated assembly device to
storage location. Close the covers.
Lock the towers.
If you have purchased lock
cores (recommended),
install them according to
your lock core instructions.
Determine your crossbar spread. Install second set of RailGrab towers and crossbar.
The accessories you will carry with your RailGrab
will determine your minimum crossbar spread (the
distance between the crossbars). Refer to the table
below to find the correct minimum crossbar spread.
*More than 2 bicycles create enough leverage on the Wheel Tray to make the longer crossbar spread necessary.
For 16” (41cm) spreads, limit bikes to 30 lbs (14kg).
