US Cargo Control L-Track Single-Stud Fittings, 4-Pack Black — 4,000 lb Break Strength, 360° Stainless O-Ring

These are four single-stud L-track fittings from US Cargo Control that convert any compatible L-track rail into flexible, heavy-duty tie-down points with a 4,000 lb assembly break strength.

Use these airline-style stud fittings to add secure anchor rings anywhere along L-track rails in trailers, truck beds, or vans. Each fitting features a spring-loaded aluminum keeper, a stainless steel O-ring that rotates 360 degrees, and a durable black powder-coat finish engineered to resist corrosion and abrasion in transport environments.

How strong are these L-track stud fittings?

Each assembly is rated with a 4,000 lb break strength, and the stud ring working loads vary by pull angle to reflect real-world forces. These ratings help you plan safe tie-down arrangements without guessing capacities.

• Assembly break strength: 4,000 lbs
• Straight pull ring rating: 1,333 lbs
• 45° ring rating: 1,000 lbs
• 90° ring rating: 667 lbs

Will these fit my existing L-track system?

Yes—these single stud fittings are compatible with common L-track styles, so you can add or rearrange anchors without replacing rails. They were designed to work on standard L-track as well as aircraft-style, angled, and recessed L-track installations.

• Works with standard L-track rails
• Compatible with aircraft-style seat track
• Fits angled and recessed L-track types
• Ideal for retrofitting or expanding current systems

How easy are they to use and reposition?

The fittings use a spring-loaded plunger mechanism so you can snap them into or remove them from the rail quickly, then slide to a new position as needed. The 360° rotating stainless steel O-ring reduces strap twist and let you direct load forces where they belong.

• Spring-loaded plunger for quick installation and removal
• 360° rotating O-ring prevents strap binding
• Lightweight black powder-coated aluminum keeper for corrosion resistance
• Reconfigures without tools in many situations

What loads and applications are these best suited for?

These stud fittings pair with cargo straps and ratchets to secure motorcycles, ATVs, UTVs, lawn equipment, appliances, and other cargo that rides in trailers or truck beds. Use multiple fittings to create redundant anchor points and spread loads across the rail.

• Secure motorcycles, ATVs, UTVs, and small vehicles
• Anchor heavy appliances and workshop equipment
• Use with textile or steel tie-downs rated appropriately
• Combine several studs for higher holding distribution

Who is this for: These US Cargo Control single stud fittings come in a 4-pack and suit fleet managers, haulers, outdoor enthusiasts, contractors, and anyone who needs adaptable, rated anchor points in trailers, vans, or truck beds. If you need a corrosion-resistant, easy-to-move L-track accessory that clearly lists working loads for different pull angles, this kit gives you quick anchors that integrate with most L-track systems.
