Extending trailer chains should only be done as a last resort and with extreme caution. The safest and recommended practice is to replace chains that are too short with chains of the correct length and rating, ensuring a direct connection to the tow vehicle’s safety chain attachment points without extensions. While extending chains might seem like a quick fix, understanding the associated risks and employing proper techniques when absolutely necessary is crucial for preventing accidents and ensuring safe towing.
The Risks and Rewards of Trailer Chain Extension
Extending trailer chains inherently introduces points of weakness into the towing system. Every connection, whether a quick link, shackle, or S-hook, represents a potential failure point. Therefore, understanding the weight rating of each component and ensuring it meets or exceeds the trailer’s Gross Vehicle Weight Rating (GVWR) is paramount. The “reward,” if it can be called that, is the ability to safely tow a trailer when properly sized chains are unavailable, but only if the extension is executed correctly and with full awareness of the increased risk.
Understanding the Legalities
Before considering any extension method, be aware of local and state laws regarding trailer towing safety. Many jurisdictions have specific regulations regarding chain length, connection methods, and required safety ratings. Ignoring these laws can result in fines, vehicle impoundment, and, more importantly, compromised safety. Consult your local Department of Motor Vehicles (DMV) or transportation authority for detailed information on towing regulations in your area.
Safe Methods for Extending Trailer Chains
If you find yourself in a situation where extending your trailer chains is unavoidable, choose the safest method possible. Always prioritize properly rated components and double-check all connections before each trip.
Using Properly Rated Quick Links
This is perhaps the most common and generally considered safest method of chain extension, provided the quick links are of the appropriate size and strength. Ensure they are proof-coil quick links designed for towing, not weaker hardware store versions.
- Determine the Required Length: Measure the amount of chain extension needed.
- Select Correct Quick Links: Choose quick links with a weight rating that meets or exceeds the trailer’s GVWR.
- Connect the Chains: Open the quick link, thread it through the end link of the trailer chain and the end link of the extension chain (if using), or the tow vehicle’s safety chain attachment point if extending directly to the vehicle.
- Tighten the Quick Link: Ensure the quick link is fully tightened using pliers or a wrench.
- Inspect the Connection: Visually inspect the connection for any signs of weakness or damage.
Utilizing Appropriately Sized Shackles
Shackles offer a robust connection but require more space than quick links. As with quick links, ensure they are appropriately rated for the trailer’s GVWR.
- Determine the Required Length: Measure the needed extension.
- Select Correct Shackles: Choose shackles with a working load limit (WLL) that meets or exceeds the trailer’s GVWR.
- Connect the Chains: Thread the shackle’s pin through the end links of both chains (trailer chain and extension chain, or directly to the vehicle).
- Tighten the Shackle Pin: Ensure the shackle pin is fully tightened. Use a wrench if necessary. Some shackles use a cotter pin for added security; ensure it is properly installed.
- Inspect the Connection: Thoroughly inspect the connection for any signs of stress or looseness.
The Danger of S-Hooks
While readily available, S-hooks are generally not recommended for extending trailer chains, even if they have a safety latch. Their open design makes them prone to accidental disengagement, especially during sharp turns or sudden stops. If you must use S-hooks in an emergency, ensure they are heavy-duty, rated for the trailer’s GVWR, and the safety latch is fully engaged. Consider securing them further with zip ties or duct tape as a temporary measure until a safer alternative can be implemented.
Maintaining Extended Trailer Chains
Regular inspection and maintenance are crucial when using extended trailer chains. Before each trip, meticulously examine all connections for signs of wear, damage, or looseness. Replace any worn or damaged components immediately.
Inspection Checklist
- Quick Links/Shackles: Check for rust, corrosion, bending, or cracks. Ensure they are properly tightened.
- Chains: Look for broken links, stretching, or excessive wear.
- Attachment Points: Inspect the tow vehicle’s safety chain attachment points for rust, cracks, or bending.
- Overall Condition: Ensure the chains are free from kinks or twists that could weaken them.
Frequently Asked Questions (FAQs) about Extending Trailer Chains
1. What is the best way to extend trailer chains if they are too short?
The best and safest way is to replace the existing chains with chains of the proper length and weight rating. This eliminates the need for extensions and reduces the risk of failure. If extension is unavoidable, use properly rated quick links or shackles designed for towing.
2. Can I just add a few links to my existing trailer chains?
Adding links can be done using quick links or shackles, but ensure these components have a working load limit (WLL) equal to or exceeding the trailer’s GVWR. Avoid using standard chain links from hardware stores, as they might not be rated for towing.
3. How do I determine the correct length of trailer chains?
The chains should be long enough to allow for turning without binding, but short enough to prevent the trailer tongue from hitting the ground if it becomes detached from the hitch. Cross the chains under the trailer tongue to create a cradle in case of separation. A general rule of thumb is that the chains should be about half the length of the trailer’s tongue.
4. What is the minimum weight rating for trailer chains?
The minimum weight rating for trailer chains should be equal to or greater than the trailer’s Gross Vehicle Weight Rating (GVWR). Always err on the side of caution and choose chains with a higher weight rating than required.
5. Are S-hooks safe for extending trailer chains?
S-hooks are generally not recommended for extending trailer chains due to the risk of accidental disengagement. If used in an emergency, ensure they are heavy-duty, rated for the trailer’s GVWR, and the safety latch is fully engaged. Consider them a temporary solution only.
6. How often should I inspect my trailer chains and extension components?
Inspect your trailer chains and all extension components before each towing trip. Pay close attention to any signs of wear, damage, or corrosion.
7. What should I do if I find a broken link in my trailer chain?
Replace the entire chain immediately. Do not attempt to repair a broken link, as this will compromise the chain’s strength and safety.
8. Can I use a bungee cord to hold up my trailer chains?
Never use bungee cords to hold up trailer chains. Bungee cords are not designed to withstand the forces involved in towing and will likely break, leaving the chains dragging on the ground.
9. What is the proper way to cross trailer chains under the trailer tongue?
Crossing the chains creates a “cradle” that can catch the trailer tongue if it becomes detached from the hitch. This prevents the tongue from hitting the ground and potentially causing more damage or loss of control. Start with each chain attached to the tow vehicle, then cross them under the trailer tongue so that the chain from the left side of the tow vehicle connects to the right side of the trailer, and vice versa.
10. Are there any alternatives to extending trailer chains?
The best alternative is to replace the existing chains with chains of the proper length. Another option, if feasible, is to reposition the safety chain attachment points on the tow vehicle, but this should be done by a qualified professional.
11. What type of chain is best for trailer safety chains?
Use proof-coil chain or high-test chain specifically designed for towing. These chains are made from higher-grade steel and have a higher weight rating than standard hardware store chains. Always check the chain’s stamp or markings to verify its weight rating.
12. Does using extended trailer chains affect my insurance coverage in case of an accident?
It could affect your insurance coverage. If an accident occurs due to a failure in improperly extended chains, the insurance company might deny coverage if they determine that negligence or a violation of safety regulations contributed to the incident. Consult with your insurance provider to understand their specific policies regarding trailer towing and chain extensions.
