4. Secure the insert tube to your vehicle using the locking hitch pin, which is passed through the
receiver tube of your vehicle and the insert tube of the Boomer, secure it with the key provided.

eliminates wobble, but does not secure the rack onto the vehicle.

the receiver tube of your vehicle.

knob(s) in a counter-clockwise direction to remove. Remove locking top plate assembly. Mount the top
tube of the bicycle on the lower rubber pad provided. Balance the bike(s) as much as possible.

Important Note: When carrying one bike, place that bike closest to vehicle.

3. When installing more than one bike, face the bikes in opposite

directions to facilitate saddle & handlebar clearance. Whenever
possible, place bikes of similar top tube diameter on same pad
group to equalize clamping pressure on the top tubes.

6. Place top plate over bicycles, and replace locking knob in

vertical threaded coupling nut. Thread the locking knob(s)
into the coupling nut, and turn in a clockwise direction to
secure bike(s) to the rack. Tighten locking knob securely,
