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

These are four US Cargo Control single-stud L-track fittings with spring-loaded aluminum keepers and 360° rotating stainless O-rings rated to a 4,000 lb assembly break strength.

Designed to create quick, flexible anchor points along any L-track rail, these compact stud fittings let you secure motorcycles, ATVs, cargo, and gear without drilling new holes or permanently altering your truck bed or trailer. Each fitting snaps into place with an airline-style plunger and locks into the track, giving you a neat, low-profile tie-down solution that moves as your load demands.

How strong are these L-track stud fittings for typical cargo?

Each stud assembly has an overall break strength of 4,000 lbs and defined stud ring ratings for directional pulls: straight, 45°, and 90°. That means they handle routine vehicle and equipment loads when used with compatible straps and proper anchor placement, but always follow working load limits for critical lifts.

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

Will these studs work with my existing L-track rail?

Yes—these single-stud fittings are built for compatibility across common L-track styles, including standard L-track, aircraft-style seat track, angled L-track, and recessed L-track. They slide into the channel and lock using the spring plunger, so installation is fast and tool-free for most users.

• Compatible with standard, aircraft, angled, and recessed L-track
• Tool-free insertion and spring-loaded locking plunger
• 360° rotating O-ring adapts to strap angles and movement
• Powder-coated aluminum body resists scuffs and surface wear

What makes these fittings durable and weather-resistant?

The fittings combine a powder-coated aluminum keeper with a corrosion-resistant stainless steel O-ring to balance strength and longevity. The spring-loaded mechanism is compact and sheltered, minimizing exposure to road grime while still allowing reliable engagement and release.

• Black powder-coated aluminum housing reduces corrosion and visible wear
• Stainless steel O-rings resist rust in harsh environments
• Sealed spring plunger design reduces dirt intrusion
• Heavy-duty construction designed for repeated use

How easy is it to reposition or remove these anchors?

Reconfiguring your tie-down layout is quick: depress the spring plunger to release, slide the stud along the track to a new slot, and let it engage. The low profile and 360° rotating ring help prevent snagging when not in use and let you angle straps without awkward twisting.

• Spring-loaded plunger for fast insertion and removal
• Low-profile keeper reduces interference with cargo
• 360° rotation for flexible strap alignment
• Pack of four lets you set up multi-point tie-downs

Who is this for: these L-track single-stud fittings suit fleet operators, weekend riders, and contractors who need dependable, movable anchor points without permanent mounting. If you transport motorcycles, ATVs, furniture, or irregular loads and already have—or plan to install—L-track rails, this 4-pack offers a rugged, corrosion-resistant solution to anchor straps, chains, or hooks while preserving flexibility in your cargo configuration.
