CARTMAN Adjustable Steering Wheel Lock — Black, Hardened Steel Anti-Theft

The CARTMAN Adjustable Steering Wheel Lock is a heavy-duty, adjustable black anti-theft device that clamps across your steering wheel to deter theft and immobilize the vehicle.

If you want a straightforward, mechanical way to make your car a less attractive target, this steering wheel lock gives visible, physical protection without electronics or wiring. Constructed from hardened steel with a pure copper lock cylinder, the device extends to suit a wide range of steering wheel diameters and comes with three cross keys for convenience. It installs and removes quickly, stores easily under a seat, and provides an obvious visual deterrent that can prevent opportunistic theft.

How does the CARTMAN lock actually stop a thief?

The device blocks steering rotation and presents a clear, hard-to-bypass barrier. Its steel body resists cutting and bending while the copper cylinder offers increased pick resistance compared with lower-grade locks.

• Hardened steel construction slows or prevents forced entry attempts.
• Pure copper lock cylinder reduces vulnerability to lock-picking tools.
• Visible across the wheel to discourage casual thieves before they try.

Will this fit my vehicle’s steering wheel?

This CARTMAN lock is adjustable to accommodate most passenger vehicles. It is designed for steering wheels with an inner diameter ranging from 7 inches to 15.7 inches, so measure your wheel before purchasing to ensure compatibility.

• Adjustable length fits small to large steering wheels within the specified range.
• Simple slide mechanism lets you set and lock the correct length quickly.
• Compact when collapsed for easy storage under your seat or in a trunk compartment.

How simple is it to use day-to-day?

Installation and removal are straightforward and take just a few minutes, making the lock practical for daily use. The included three cross keys let you keep a spare set while you store one on your key ring or in a household safe location.

• Quick clamp-and-lock action — no tools required.
• Three cross keys provided; manufacturer does not retain spare keys for security.
• Lightweight enough to carry yet sturdy enough for effective deterrence.

What maintenance or care does it need?

The CARTMAN lock requires minimal upkeep to remain dependable. Occasional lubrication of the lock cylinder and wiping the steel surfaces to remove moisture will extend lifespan and maintain smooth operation.

• Apply graphite or silicone lubricant to the lock cylinder as needed.
• Wipe down metal surfaces to prevent surface rust if exposed to moisture.
• Store in a dry place when not in use to preserve finish and mechanism.
