Heavy Duty Spring Toggle Latch for Truck & Trailer Side Doors

This galvanized spring toggle latch is specially engineered for cargo trailers, truck side panels, Kobelco excavator access doors, and box body enclosures, delivering reliable locking performance for heavy-load transport vehicles.

Key Features

1. Robust Galvanized Steel Construction Whole body made of high-strength carbon steel with hot-dip galvanized finish, offering excellent rust, corrosion and oxidation resistance. It withstands harsh outdoor environments including coastal humidity, rain and mud for long service life.
2. Self-Locking Spring Mechanism Built-in thickened tension spring provides constant clamping force to eliminate loose rattling during vehicle driving. The automatic rebound design ensures tight door closure and prevents accidental opening on bumpy roads.
3. Adjustable Locking Stroke The movable bolt head allows fine adjustment of tightness, compensating door gap deviation caused by long-term vibration or deformation. Easy to install and fit different door panel thicknesses.
4. Heavy-Duty Load Capacity Precision stamping integrated structure enhances tensile strength, perfectly matching the weight demand of large trailer side doors and excavator maintenance access panels.
5. Universal Mounting Dimension Standard mounting hole layout with total length 309.5mm, compatible with most mainstream trailer, truck and engineering vehicle door frames. Simple bolt-on installation without complicated modification.
