4. Setup and Installation
The ANZO USA 851011 clamps are designed for straightforward installation. Follow these steps to securely mount your fog lights:
- Identify Mounting Location: Choose a suitable 1.5-inch diameter bar or tube on your vehicle where you intend to mount your fog lights. Ensure the location provides adequate clearance for the lights and does not obstruct any vehicle functions or lighting.
- Prepare the Clamp: The clamp consists of two halves. Separate the two halves by loosening the hex screw located at the bottom of the clamp.
- Position the Clamp: Place one half of the clamp around the chosen bar. Then, align the second half and bring them together around the bar.
- Initial Fastening: Insert the hex screw and hand-tighten it to hold the clamp in place. Do not fully tighten at this stage.
- Attach Fog Light: Secure your fog light or other accessory to the mounting tab of the clamp using appropriate hardware (not included with the clamp). Ensure the light is oriented correctly.
- Adjust and Final Tighten: Adjust the position of the clamp and the attached light as needed. Once the desired position is achieved, use a hex key to firmly tighten the hex screw on the clamp. Ensure the clamp is snug and does not rotate or slide on the bar. Periodically check the tightness of the clamp after initial use.
Note on Fitment: While designed for 1.5-inch bars, some users have reported that the clamp may be slightly oversized, potentially leading to a less-than-perfect fit on true 1.5-inch diameter tubes. If you experience this, consider using a thin rubber shim or similar material between the clamp and the bar to ensure a secure, vibration-free fit. This can also help protect the finish of your vehicle's bar.

5. Usage and Functionality
Once properly installed, the ANZO USA 851011 mounting clamps provide a stable platform for your fog lights or other accessories. The billet aluminum construction ensures durability and resistance to the elements. The black anodized finish offers protection against corrosion and blends seamlessly with most vehicle aesthetics. Ensure that any attached lights are wired correctly according to their manufacturer's instructions and local regulations.
6. Maintenance
- Regular Inspection: Periodically inspect the clamps and attached lights for any signs of loosening, damage, or corrosion. This is especially important after off-road use or exposure to harsh weather conditions.
- Cleaning: Clean the clamps with a mild automotive cleaner and a soft cloth. Avoid abrasive cleaners or harsh chemicals that could damage the anodized finish.
- Fastener Check: Re-tighten the hex screws if any looseness is detected. Do not overtighten.
7. Troubleshooting
- Clamp is Loose on Bar: If the clamp does not tighten sufficiently on a 1.5-inch bar, it may be slightly oversized. Insert a thin, durable rubber or plastic shim material between the clamp and the bar to achieve a tighter fit.
- Light Vibrates: Ensure the clamp is fully tightened to the bar and the light is securely fastened to the clamp's mounting tab. Check for any play in the light's own mounting hardware.
- Corrosion or Finish Damage: While anodized for protection, extreme conditions or impacts can damage the finish. Clean regularly and consider touch-up paint if minor damage occurs to prevent further corrosion.
