Product Overview
The BAL Lock-Arm Stabilizing Bar is designed to enhance the stability of your recreational vehicle (RV) by connecting the jack leg or foot directly to the trailer's frame. Its unique swivel mount allows it to adapt to most crank-down trailer jacks and function effectively at various jack angles, providing a secure and stable foundation for your RV when parked.

Setup and Installation
Proper installation of the Lock-Arm Stabilizing Bar is crucial for optimal performance and safety. Follow these steps carefully:
- Prepare the RV: Ensure your RV is parked on a level surface and the primary leveling jacks are deployed and stable.
- Identify Mounting Points: The Lock-Arm Stabilizing Bar is designed to attach to the jack leg or foot and a suitable point on the trailer's frame. Locate a sturdy, accessible section of the frame near each jack you intend to stabilize.
- Attach to Jack: Position the swivel mount of the stabilizing bar onto the leg or foot of the RV's crank-down jack. The unique design allows for adaptation to various jack angles. Secure the attachment point firmly.
- Attach to Frame: Extend the other end of the stabilizing bar to reach the chosen point on the trailer's frame. Secure this end using the provided hardware. Ensure a snug fit without over-tightening, allowing for slight articulation if necessary.
- Repeat for All Jacks: Install a Lock-Arm Stabilizing Bar on each jack that requires additional stabilization.
- Verify Stability: After installation, gently test the stability of the RV by applying slight pressure to different areas. The RV should feel significantly more stable.
Note: Always refer to your RV's manufacturer guidelines for specific recommendations regarding stabilization and frame attachment points.
Operating Instructions
Once installed, the Lock-Arm Stabilizing Bar works in conjunction with your RV's existing leveling jacks to minimize movement and sway.
- Before Deployment: Ensure the stabilizing bars are securely attached to both the jack and the frame.
- Deploying Jacks: Operate your RV's crank-down jacks as usual. As the jacks extend and make contact with the ground, the Lock-Arm Stabilizing Bar will provide lateral support, reducing side-to-side motion.
- Retracting Jacks: Before moving your RV, fully retract all leveling jacks. The stabilizing bars will naturally disengage or fold with the jacks. Ensure they are clear of any obstructions before driving.
- Storage: When not in use, ensure the stabilizing bars are properly secured to prevent rattling or damage during transit.
Maintenance
Regular maintenance will prolong the life and effectiveness of your BAL Lock-Arm Stabilizing Bar.
- Cleaning: Periodically clean the stabilizing bar with mild soap and water to remove dirt, grime, and road salt. Rinse thoroughly and dry.
- Lubrication: Apply a light coat of silicone spray or a similar lubricant to the swivel points and any moving parts to ensure smooth operation and prevent corrosion. Do this annually or as needed.
- Inspection: Before each trip and periodically during extended stays, inspect the bar for any signs of wear, damage, bending, or loose fasteners. Check the attachment points on both the jack and the frame for security.
- Corrosion: If any rust or corrosion is observed, clean the affected area and apply a rust-inhibiting primer and paint to protect the metal.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| RV still sways after installation. | Loose attachment points; insufficient number of stabilizing bars; primary jacks not fully deployed or on uneven ground. | Ensure all fasteners are tight. Consider installing additional stabilizing bars if your RV is particularly long or heavy. Verify primary jacks are fully extended and RV is level. |
| Difficulty attaching the bar. | Incorrect positioning; obstruction; incompatible jack type. | Adjust the angle and position of the swivel mount. Clear any debris. Confirm your jack is a compatible crank-down type. |
| Squeaking or grinding noise during operation. | Lack of lubrication; dirt or debris in moving parts. | Clean and lubricate all swivel points and moving parts with a suitable lubricant. |
| Bar appears bent or damaged. | Impact during transit or use; excessive force applied. | Discontinue use immediately. Replace the damaged bar to ensure safety and proper stabilization. |
