The TGL3410ST is a steel latch assembly designed for dump bodies and trailers. It uses a welded A-36 steel bar with a forged bracket and clevis. A secure secondary locking mechanism helps prevent unintentional tailgate opening during transport. Best for operators who need a robust, long-lasting solution on demanding job sites and roadways.

Best for: fleet operators and outfits with welded tailgate systems who want extra protection against accidental openings. This model is suited for those prioritizing a strong locking point and a tight seal against debris leakage.

Limitation to note: installation requires welding or compatible fabrication work, so it’s less ideal for DIY swaps on non-welded tailgates.

Buying Guide: Tailgate Lock Considerations

• Material and construction: Look for heavy-duty steel (A-36 or equivalent) for durability in harsh weather and loads.
• Secondary locking: A secondary lock adds an extra layer of security against accidental openings during transport.
• Weld-on vs. bolt-on: Weld-on designs provide a tight seal and robust performance but require fabrication work; bolt-on variants are easier to install on existing bodies.
• Compatibility: Ensure the latch matches your tailgate model numbers (TGL34SBR, TGL3410ST, TGL3410SS, etc.) and your vehicle’s body design.
• Seal quality: A good tailgate seal prevents material leakage, reducing cleanup and road hazards.
• Maintenance: Choose designs with corrosion resistance to extend service life in rain, snow, and mud.
• Installation considerations: Consider whether your fleet has in-house fabrication capabilities or requires a ready-to-install kit.
