3. Setup and Installation
Important Safety Note: Always ensure the crossbars are securely fastened before driving. Periodically check tightness, especially after initial installation and before long trips.
3.1 Identifying Front and Rear Crossbars
The front crossbar is longer than the rear crossbar. Each bar also has a distinct aerodynamic profile: the rounder side should face the front of the vehicle, and the pointier side should face the rear.

Image: Size details for front and rear crossbars, indicating the front bar is longer.
3.2 Assembling the Crossbars and Bases
- Unlock the Base: Use the provided key to unlock the cover on each base. Remove the cover to expose the screw mechanism.
- Loosen Screws: Using the Allen wrench, slightly loosen the screws inside the base. Do not remove them completely. This allows the lower clamp to move freely.
- Attach Crossbar to Base: Slide the end of a crossbar into the open slot of a base. Ensure the aerodynamic profile is correctly oriented (rounder side forward).
- Insert Screws (Do Not Tighten): Place the screws into the designated holes on the base, but do not tighten them yet. This allows for length adjustment.
- Adjust Length: The left and right length of the crossbar can be adjusted by sliding the bar within the base.

3.3 Mounting to Vehicle Roof Rails
- Position the Assembly: Place the assembled crossbar onto your vehicle's existing side rails. The lower clamp of the base should fit securely under the side rail.
- Tighten Screws: Once positioned correctly, use the Allen wrench to firmly tighten the screws within the base. Ensure the crossbar is stable and does not move.
- Lock the Cover: Replace the cover on the base and lock it with the key. This secures the installation and provides anti-theft protection.

Note: The front crossbar is typically installed further forward to accommodate the vehicle's roof curvature. Ensure both bars are parallel and evenly spaced for optimal load distribution.
4. Operating Instructions
4.1 Load Capacity
The HmmtyRack cross bars support a maximum load capacity of up to 300 lbs (136 kg). However, always refer to your vehicle's owner's manual for its specific roof weight limit. Do not exceed the lower of these two limits.

4.2 Securing Cargo
Utilize appropriate tie-down straps and accessories to secure your cargo to the cross bars. Ensure cargo is evenly distributed and does not obstruct your view or interfere with vehicle operation. The bases include tie-down loops for easy rope and item securing.

4.3 Aerodynamic Design
The cross bars feature an aerodynamic design to minimize wind resistance and noise. While designed to reduce noise, some wind noise may still be noticeable at higher speeds, especially with certain cargo types.

5. Maintenance
- Regular Inspection: Periodically inspect all mounting points, screws, and the crossbars themselves for any signs of wear, damage, or loosening. Tighten any loose fasteners immediately.
- Cleaning: Clean the cross bars with mild soap and water. Avoid abrasive cleaners or solvents that could damage the finish.
- Lubrication: For the lock mechanisms, a light spray of lubricant can help maintain smooth operation and prevent corrosion, especially in harsh weather conditions.
- Seasonal Removal: If the cross bars are not in use for extended periods, especially during seasons when they are not needed, consider removing them to reduce potential wear and tear and improve fuel efficiency.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Crossbars feel loose after installation. | Screws not tightened sufficiently. | Re-tighten all screws using the Allen wrench until secure. Ensure the lower clamp is properly seated under the side rail. |
| Excessive wind noise. | Incorrect orientation of crossbars; cargo not aerodynamically loaded. | Ensure the rounder side of the crossbar faces forward. Adjust cargo placement for better aerodynamics. Consider adding a wind fairing if noise persists. |
| Keys are missing or lost. | Misplaced keys. | Contact HmmtyRack customer support for replacement keys or assistance. Note that the package includes two keys. |
| Sunroof interference. | Improper installation or incompatible vehicle. | Ensure crossbars are installed according to instructions. These crossbars are designed not to interfere with sunroof operation on compatible vehicles. If interference occurs, recheck installation or vehicle compatibility. |
