Step 2
Align and slide a tire / frame hook assembly
(#3) onto the arm of the tray assembly (#1)
as shown. Ensure the hook is facing inward
toward the tray and the release button

aligning the holes in each. Proceed to
assemble with hardware (#5, #12, #13
and #14) as completed in step 4.
Step 4
Orientate the tray assembly with the CURT logo
onto the shank assembly (#2) as shown. Align
the tray holes with those in the shank assembly.
Place a tray spacer (#5) onto the tray, aligning
its holes with those in the tray. Insert two 3/8"
carriage bolts (#12) through the spacer, tray and
shank assembly. Place a 3/8" flat washer (#13)
and 3/8" nylock nut (#14) onto each bolt.
Tighten each nut firmly with the

Step 7
To adjust the rack between vertical, horizontal
and tilted positions, squeeze the trigger on the
handle and rotate clockwise. Adjust the rack
position and release the handle. A 'click' will
be heard when the rack reaches its horizontal
or vertical position.
Step 8
With the rack positioned horizontally, place a
bike onto one of the trays with the front tire
nested into the wheel basket. Raise the arm
with the hook assembly into position over the
tire and frame. Depress and hold the hook
assembly lever while sliding the hook assembly
along the arm if adjustment is necessary for
positioning. Push the hook downward
into position firmly as shown.
NOTICE
For bikes equipped with a fork-mounted
brake caliper, take care not to damage
the caliper with excessive force.
Step 9
To discourage theft, pull the locking cable
from the arm and pull through the bike frame.

pull the strap firmly through the latch.
To remove the strap, press and hold the release
lever while pulling the strap from the latch.
Step 11
To allow rear-vehicle access, the rack can be
tilted away from the vehicle. Support the rack
while rotating the release handle clockwise
allowing the rack to stop at its lowest position.
WARNING
When transporting heavier bikes such
as e-bikes, a team lift may be required
when changing rack positions to prevent
injury and / or product damage.
Do not transport the rack in the lowest position as
this may cause damage to the product or cargo.
Step 12
When transporting the rack with an empty tray
or trays, the rack components must be secured
as shown. Place the tire / frame hook beneath
the tray. Slight downward pressure on the
arm may be necessary while sliding the hook
inward. Ensure the wheel strap is buckled
and the cable is inserted fully into the arm.
When unloaded, the rack may be
transported in the vertical position.
