Master Lock Cable Bike Lock 4 ft 5/16" Two-Pack — Preset 4-Digit Combo, Vinyl-Coated Braided Steel

Two preset four-digit combination cable locks from Master Lock provide 4 ft of vinyl-coated braided steel security for bikes and outdoor gear without keys.

If you need a flexible, keyless way to secure bicycles, scooters, strollers or other outdoor items, the Master Lock 8143T two-pack delivers convenient protection with durable materials and a reusable combination. Each cable measures 4 feet long and uses 5/16-inch braided steel wrapped in a vinyl jacket to reduce scratches on painted surfaces. Both cables share the same preset code for quick setup and day-to-day convenience, backed by Master Lock’s lifetime guarantee.

How does this cable lock keep my bike protected during short stops?

The braided steel core resists casual snips and the vinyl coating prevents damage to frames while locking to immovable objects. The four-digit combination eliminates keys so you can lock and go without fumbling for metal.

• 5/16" (8 mm) braided steel cable for cut resistance and flexibility
• 4 ft (1.2 m) length to loop around most bike frames and posts
• Vinyl outer layer protects paint and resists moisture
• Preset 4-digit combo on each cable; both share the same code

Can I use these locks for gear besides bicycles?

Yes — their flexible length and durable construction make them suitable for a wide range of outdoor equipment. Use them to secure strollers, scooters, e-bikes, kayaks, or lawn gear when you need a temporary, reliable hold.

• Loop through wheel and frame or around accessory attachment points
• Fits small posts, racks, and railings at parks and storefronts
• Two cables let you secure multiple items with the same combination
• Lightweight enough for daily carry in a bag or basket

What makes the preset combination practical, and can it be changed?

The preset four-digit code means you can start using the locks right away without programming — handy for shared use or gifting. These model cables are designed for keyless convenience; follow the included instructions to confirm whether your set allows resetting the combination.

• Preset factory code for immediate use straight from the package
• Keyless operation avoids lost or duplicate keys
• Instructions included for checking or changing codes when supported
• Both cables in the pack use the same preset code for uniformity

How durable is the cable and how does it perform outdoors?

The braided steel core delivers flexibility and resistance to casual tampering, while the vinyl jacket shields the metal and prevents scratches. Built to handle daily outdoor exposure, these cables perform well for short-term parking and securing gear in low-to-moderate risk areas.

• Braided steel core balances strength and pliability for easy looping
• Vinyl jacket protects finishes and reduces weather exposure
• Compact 4-foot length works for most everyday locking scenarios
• Two-pack increases redundancy and allows multi-item security

It’s a practical choice when portability, frame protection, and quick operation matter more than heavy industrial-grade theft resistance.
