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

US Cargo Control Single Stud L-Track Fittings (4-pack) are compact, spring-loaded anchor points for L-Track rails that provide a 4,000 lb assembly break strength and a rotating stainless-steel O-ring for flexible tie-downs.

These single-stud fittings give you four corrosion-resistant anchor rings that lock into any L-Track rail for fast, adjustable tie-downs. Finished in black powder coat with an aluminum keeper and spring-loaded plunger, each fitting delivers high tensile capacity while staying lightweight and easy to reposition. They’re built to work with cargo straps, winch straps, and other tie-down hardware used for motorcycles, ATVs, tools, and freight in trucks, vans, and trailers.

How do these L-Track fittings attach and move along the rail?

The fittings use an airline-style stud that slides into standard L-Track slots and locks with a spring-loaded plunger. To reposition, press the plunger, lift slightly and slide the stud to a new location; release to lock it in place. The 360-degree rotating O-ring helps align straps without twisting.

• Spring-loaded plunger for quick insertion and release
• Works with Standard, Aircraft-style, Angled, and Recessed L-Track
• 360° rotating stainless steel ring for strap alignment
• Lightweight aluminum keeper with black powder-coat finish

What load ratings and safety margins should I expect?

Each stud assembly lists a 4,000 lb break strength for the full assembly and measured stud ring working loads at varying angles. Use the straight pull rating when possible for maximum capacity and reduce the load as angle increases. These values help you choose the right placement and number of anchors for safe restraint.

• Assembly break strength: 4,000 lbs
• Straight pull stud ring rating: 1,333 lbs
• 45° pull rating: 1,000 lbs; 90° pull rating: 667 lbs
• Stainless O-ring and powder coat resist corrosion in varied environments

Will these fittings work with my straps and vehicle setup?

Yes — they’re designed to accept most cargo straps and hooks that loop around a 360° ring. Combine them with cam straps, tie-down webbing, or D-ring adapters to create anchor points tailored to your load and vehicle. Their compact profile keeps straps snug while allowing fast reconfiguration between hauls.

• Compatible with cam straps, ratchet straps, and soft loop attachments
• Low-profile design minimizes interference in tight cargo spaces
• Four-pack provides multiple tie-down locations for balanced restraint
• Ideal for truck beds, enclosed trailers, cargo vans, and UTV trailers

How do I maintain these anchors for long life?

Maintenance is minimal: keep the plunger and ring free of debris, rinse off road salt or mud, and inspect for wear before heavy use. The stainless-steel ring and powder-coated aluminum housing reduce corrosion, but periodic checks ensure reliable performance over time.

• Rinse after exposure to saltwater or heavy road grime
• Lubricate plunger lightly if movement becomes stiff
• Inspect rings and studs for deformation or cracks regularly
• Replace any damaged fitting; continue using the rest as needed

Who is this for: Professionals and DIY haulers who need flexible, durable anchor points on L-Track systems — including fleet operators, vehicle owners securing powersports, freight handlers, and contractors who want quick, adjustable tie-downs with a high break strength and corrosion-resistant hardware. The 4-pack gives enough anchors to set up balanced tie-down schemes for motorcycles, ATVs, equipment, or cargo that require dependable restraint while remaining easy to reposition for changing loads.
