5. Installation
The MTNTOPCN Military Design Pickup Roll Bar offers adjustable width for compatibility with various truck models. Installation methods may vary slightly depending on whether your truck has a tonneau cover.
5.1 General Assembly Steps
- Prepare Components: Lay out all roll bar components and hardware on a clean, flat surface. Ensure all parts are accounted for as per the package contents.
- Assemble Main Body Sections: Connect the main body sections of the roll bar using the provided M6 x 20 bolts and flat washers. Ensure all connections are secure but do not fully tighten until the entire assembly is complete.
- Attach Crossbars: Secure the front and rear crossbars to the main body using the specified M6 x 20 bolts and flat washers.
- Install Trailer Hitch (if applicable): Attach any trailer hitch components to the designated points on the roll bar.
5.2 Mounting to Truck Bed
There are two primary installation scenarios:
- Installation on a truck without a tonneau cover: Drilling into the truck bed rails is required.
- Installation on an MTNTOPCN Retractable Hard Tonneau Cover or other compatible retractable tonneau covers with flat tracks: This is a bolt-on installation.
- Position Roll Bar: Carefully place the assembled roll bar onto the truck bed rails.
- Adjust Width: Measure the width of your truck's rear cargo bed. Adjust the width of the roll bar to match this measurement (e.g., if width is 1611mm, adjust the roll bar to 1611mm). This is typically done by sliding the adjustable sections and securing them with M8 x 20 hex bolts and flange nuts.
- Secure to Truck Bed:
- For trucks without a tonneau cover: Mark and drill 11mm holes through the truck bed wall where the mounting brackets align. Insert M10 x 35 bolts and tighten them to secure the roll bar. (Three bolts on each side).
- For compatible tonneau covers: Insert M10 x 35 screws into the clamping slots of the tonneau cover tracks. Adjust the gap between the screws to align with the roll bar's mounting points. Place the roll bar onto the tracks and secure it by tightening the screws.
- Connect Wiring: Connect the wiring for the integrated brake light and any auxiliary lights according to your vehicle's electrical system. Professional installation for wiring is recommended if you are unfamiliar with automotive electrical systems.
- Final Tightening: Once the roll bar is correctly positioned and aligned, fully tighten all bolts and nuts to ensure a secure installation.

7. Maintenance
To ensure the longevity and optimal performance of your MTNTOPCN Military Design Pickup Roll Bar, follow these maintenance guidelines:
- Regular Cleaning: Clean the roll bar regularly with mild soap and water to remove dirt, dust, and road grime. Avoid abrasive cleaners or harsh chemicals that could damage the textured black finish.
- Fastener Inspection: Periodically check all bolts, nuts, and mounting hardware for tightness. Vibrations from driving can cause fasteners to loosen over time. Re-tighten as necessary.
- Corrosion Check: Inspect the roll bar for any signs of rust or corrosion, especially after exposure to harsh weather conditions or off-road use. Address any corrosion promptly with appropriate rust treatment and touch-up paint to maintain the finish.
- Wiring Inspection: Check all electrical connections and wiring for the integrated lights. Ensure wires are securely routed and free from chafing or damage.
8. Troubleshooting
Below are common issues and their potential solutions:
- Issue: Roll bar feels loose or rattles.
Solution: Inspect all mounting bolts and nuts. Tighten any loose fasteners. Ensure the roll bar is correctly seated on the truck bed rails or tonneau cover tracks. - Issue: Integrated lights are not working.
Solution: Check all electrical connections for the lights. Ensure wires are properly connected to the vehicle's power source and ground. Verify that the light bulbs or LEDs are not damaged. Check relevant fuses in your vehicle's fuse box. - Issue: Difficulty adjusting width or height.
Solution: Ensure all adjustment bolts are sufficiently loosened before attempting to slide components. Clean any dirt or debris from the sliding mechanisms. Apply a small amount of silicone lubricant if movement is stiff.
