(To secure a trailer in your driveway with chains, anchor Grade 70 or stronger chains tightly around the axle or frame and lock them to a concrete-set ground anchor using a weather-resistant, high-security padlock.
How to Chain Your Trailer the Right Way (So Thieves Walk Away)
Securing your trailer with chains is one of the most reliable ways to stop theft, if done right.
But most setups fail at the exact points thieves know to target: weak anchor spots, exposed padlocks, or removable parts like wheels and jacks. To protect your trailer effectively, here’s what matters most:
-
Always use hardened Grade 70 chains (3/8"–1/2") to resist bolt cutters
-
Anchor chains to concrete or ground bolts, not fences or vehicles
-
Wrap chains tightly around the axle or frame, not wheels or jacks
-
Use puck-style or shrouded padlocks that resist cutting and corrosion
-
Add a second chain if possible to increase time and effort for thieves
-
Reduce chain visibility and place locks in low-clearance areas
-
Avoid universal-fit coupler locks that leave safety chains exposed
Security is about making your trailer too difficult, noisy, or time-consuming to steal.
When chains are used correctly, and combined with layered protection, you make your trailer a hard target. Even if you stop here, you’ll have a smarter setup.
But if you want to go beyond the basics and fully lock down your trailer from every angle, keep reading.
Why Trailer Theft from Driveways Is So Common (and So Easy)
Even parked just outside your home, your trailer isn’t as safe as you might think.
Driveway theft is one of the easiest crimes to commit because trailers are low-hanging fruit, no factory alarms, no ignition systems, and most are secured improperly or not at all.
1. Trailer Thefts Are Happening More Often
Trailer theft has surged in recent years. Organized crews scout residential areas specifically looking for unsecured hauls.
Light trailers, even with locked wheels, can be tilted or lifted by two people and rolled away.
2. Thieves Just Hook Up and Drive Off
It’s surprisingly common: thieves show up with a truck and a universal hitch.
If the trailer isn’t locked properly or the chains aren’t anchored, it’s gone in under 60 seconds. No damage, no noise, no alerts.
3. Thieves Target Easy Wins, Not Just Expensive Rigs
Don’t assume your trailer is too old or too basic to be a target. Thieves often go for whatever is easiest to steal, not necessarily what’s most valuable.
If it’s light, accessible, and unsecured, it’s on their radar regardless of price tag or condition.
4. Parking at Home Doesn’t Guarantee Safety
Driveways feel safe, but they’re often easy targets. Predictable routines, no surveillance, and clear access make them ideal for thieves.
Just being close to your house doesn’t mean your trailer is secure, visibility and access matter more.
5. Weak Anchors Make It Easy for Thieves
Chaining your trailer to a fence, jack, or bumper doesn’t offer real protection. These parts can be cut or removed in minutes.
The BEST protection for your trailer!
For chains to work, they need to connect to something solid like concrete or a ground anchor.
To stop trailer theft, you need more than a lock. You need a system. Let’s walk through how to chain your trailer effectively, and what most people get wrong.

Using Chains to Secure Your Trailer: What Works, What Doesn’t
Chains are one of the most cost-effective ways to protect a trailer, but only if they’re used the right way.
Many setups fail not because the chain is weak, but because it’s placed or anchored poorly.
1. Run the Chain Through Your Axle or Frame, Not the Wheels
Wheels can be rolled or removed, which makes them a weak spot. A thief can slice through a wheel spoke or take the whole wheel off.
The axle or frame is much harder to defeat. These components are solid, welded, and not easily accessed.
Avoid wrapping chains around tongue jacks, fenders, or any parts that can be removed with basic tools.
2. Anchor Your Chain Into Concrete, Not Your Fence
Even the strongest chain is useless if it’s tied to something weak. Fences, tree trunks, or car bumpers can all be cut or moved.
A better method is to drill into the concrete and use an eye bolt set in epoxy or Sakrete. Low-profile ground anchors are another great option, they sit flush with the driveway and are hard to tamper with.
3. Use Grade 70 or Higher Chains Only
Not all chains are equal. Grade 70 or higher transport chains are built to handle serious force. Chains between 3/8" to 1/2" thick are especially tough to cut with bolt cutters.
Standard hardware chains might look tough but are often easy to break with basic tools.
4. Wrap Chains Tightly and Use Sheathing
Slack gives thieves leverage. Wrapping the chain tightly around your axle or frame limits movement and makes cutting harder.
Sheathing the chain with pipe or protective sleeves adds another layer of difficulty and helps guard against rust.
5. Use Hidden or Low-Clearance Placement
If thieves can’t get to the chain, they can’t cut it. Positioning it low or tucked away makes it harder to reach.
Some locks are designed to reduce clearance under the coupler, making tool access nearly impossible.
6. Pair Chains With High-Security Padlocks
Even the strongest chain needs a strong lock. Use shrouded padlocks, puck-style locks, or weather-resistant Abloy-style cores.
In cold or wet areas, choose locks built to resist corrosion, rust can take down your setup just as fast as theft.

7. Use Two Chains When Possible
One chain is good. Two is better. Securing both sides of the trailer or using two anchor points forces thieves to do more work.
Even small trailers benefit from this extra layer of security.
A chain setup is only as strong as its weakest point. Next, we’ll look at why chains alone aren’t enough, and what you can add for full protection.

Why Chains Alone Aren’t Enough: Layered Trailer Security for Real Protection
Layers of Security- Proven Industries
Chains are a strong start, but they aren’t enough on their own.
Smart thieves look for exposed weaknesses, and a single lock or chain often isn’t enough to stop them. A layered approach adds time, noise, and effort, all things thieves want to avoid.
-
Coupler locks that cover chains: Some locks, like select models from Proven Industries, enclose both the coupler and safety chains, blocking easy access to key points of attack.
-
Wheel locks for extra friction: A visible wheel boot makes towing harder and more time-consuming, especially when combined with chains or parking barriers.
-
Tight parking limits access: Backing into a wall or placing another vehicle in front of your trailer can block thieves from getting a clean angle to hitch and go.
-
Light and cameras help: Motion lights and security cameras make it harder for someone to approach unnoticed. Visibility discourages theft.
-
Alarms and GPS add alerts: Tilt alarms and GPS trackers can alert you the moment your trailer is tampered with, helping prevent or recover theft.
-
Remove parts when idle: Removing a wheel or coupler component makes towing almost impossible without tools or time, both things thieves hate.
-
Custom details scare buyers: Decals, etching, or bright colors make trailers easier to identify and harder to resell on the black market.
No single solution can fully protect a trailer, but combining several makes it much harder to steal. The goal is to create just enough resistance and visibility to make your trailer more trouble than it’s worth.
