Curt MFG Part 23666 1-Year Warranty Curt 23666 Multi-Use Cable Lock -- 6 ft Braided Steel, Vinyl Coated

Whether you're securing a bicycle at a trailhead, locking down an ATV on a carrier, or keeping watercraft gear in place at camp, the Curt 23666 gives you a flexible, weather-resistant cable lock you can use across all your equipment. The 6 ft braided steel cable with a 3/8 in diameter is long enough to loop through frames, racks, and hitches, while the vinyl coating guards against rust and surface scratches.

Versatile Security for RVers and Outdoor Enthusiasts

RV trips rarely involve just one piece of gear. From bikes on rear racks to kayaks on the roof, ATVs on a flatbed, or a lawn mower at the storage unit, the Curt 23666 is built to move between tasks. Its cinching lock body lets you adjust the cable loop to snug up around different frame shapes and diameters without leaving slack that defeats the purpose of a lock.

The braided steel construction resists simple cut attempts better than solid single-strand cable, and the vinyl jacket keeps the cable from scratching painted bike frames, ATV plastics, or your RV's finish. Two keys are included so you have a backup on hand.

6 ft Braided Steel Cable

Long enough to loop through multiple frame points or around a rack post. Braided construction adds resistance over single-strand cable.

Vinyl Rust-Resistant Coating

Black and orange vinyl jacket protects the steel core from moisture and prevents surface scratches on gear and racks.

Cinching Lock Mechanism

Adjustable cinching action lets you tighten the cable loop to fit frames and posts of varying sizes with minimal slack.

Two Keys Included

Comes with two matching keys so you can keep one accessible and store a backup at camp or in your tow vehicle.

Common RV and Outdoor Applications

The Curt 23666 is well suited for situations where you need a single lock to serve multiple roles across a camping trip or storage run:

  • Securing bicycles through frame and wheel to a hitch rack or fixed post
  • Locking ATVs or UTVs to a trailer rail or tiedown ring
  • Anchoring watercraft accessories, paddles, or small boats to a dock cleat or trailer
  • Looping through lawn and garden equipment handles to a fixed structure
  • Adding a secondary lock layer to a cargo carrier or roof rack load
Cable Length Advantage: At 6 ft, this cable is long enough to pass through a bicycle frame and both wheels simultaneously, or to loop from an ATV frame around a trailer rail and back -- a significant advantage over 4 ft locks that force you to choose one anchor point.

Construction and Weather Resistance

The braided steel core is the structural backbone of the lock. Braiding means the individual strands share load and resist cutting tools that would slice through a single strand more easily. The vinyl coating serves two purposes: it keeps oxygen and moisture off the steel to prevent rust, and it protects surfaces from being marred when you thread the cable through painted or powder-coated frames.

The lock body itself houses the key cylinder and the cinching mechanism. The black and orange color scheme makes the lock easy to spot in a gear bag so you're not digging for it when you need it.

Note on Security Level: Cable locks of this diameter are appropriate for deterrence and convenience security -- locking gear at a campsite, securing equipment on a carrier during transit, or adding a secondary layer to a locked enclosure. For high-theft environments or extended unattended storage, a heavier-gauge chain lock or ground anchor system provides a stronger barrier.
Maintenance Tip: Every few months, work a small amount of graphite-based lock lubricant into the key cylinder to keep it turning smoothly, especially after rain or exposure to road spray. Avoid oil-based lubricants that can attract grit and gum up the mechanism.

What Is Included

  • 1x Curt 23666 cable lock with cinching body
  • 2x matching keys
Pairs Well With: If you're securing a bike rack itself to the hitch, look for a Curt hitch receiver pin lock that locks through the anti-rattle bolt hole. Using the cable lock on the bikes and a pin lock on the rack together gives you two independent security layers with matched Curt hardware.

Important Information
  • This cable lock is a deterrence-grade security device. It is not rated or certified as a theft-proof device for high-risk, unattended, or extended outdoor storage situations.
  • Do not use as a primary restraint for securing cargo during highway transport -- use rated load straps or chains for that purpose.
  • Store keys separately from the lock. Losing both keys means the lock must be cut to remove it.
  • Inspect the cable periodically for kinks, fraying, or corrosion at the end fittings. A compromised cable should be replaced.
  • Warranty covers manufacturing defects for 1 year from date of purchase. Physical damage, cutting, and wear are not covered.
