Connection type
Receiver, coupler, king-pin and gooseneck systems require different lock geometry.
TOWING GEAR
Understand hitch-pin, coupler, receiver, fifth-wheel and gooseneck security products and how the correct lock depends on the connection you actually use.
WHAT MATTERS
TowGauge separates vehicle identity, manufacturer ratings, vehicle-specific inputs and equipment guidance instead of treating them as one data source.
Receiver, coupler, king-pin and gooseneck systems require different lock geometry.
Some products secure a connected hitch while others are designed for an uncoupled trailer.
Corrosion resistance, dust protection and key-cylinder design matter for equipment that lives outside.
HOW IT WORKS
Start with the actual hitch/coupler system.
Connected towing, parked vehicle or stored trailer.
Use the lock manufacturer's dimensional fitment requirements.
TOWGAUGE
Start with the source-backed vehicle and build the towing decision from there.
