Premium Swing-Away Trailer Lock For Boat Trailers
The Trimax TH6 is a swing-away trailer lock designed to secure a trailer when detached from the tow vehicle. Best for boat trailer owners who want extra security when parking or storing the trailer. This lock uses heavy-duty steel for durability and resistance to tampering. It may be more than needed for casual use, but it provides strong protection for frequent park-and-store scenarios.
Who it’s best for: Boat owners who park their trailers in public spaces or storage lots. Why selected: It adds a layer of security beyond a simple hitch pin. Caution: It is a lock, not a pin; ensure you still have a compatible hitch pin or coupler pin for daily towing.

Buying Guide
Key factors to consider when choosing a boat trailer swing tongue pin or related hitch pin:
- Pin diameter and length: Ensure a snug fit with your trailer’s hitch hole to prevent wobble or disengagement.
- Material and finish: Stainless or coated steel resists rust in marine environments; consider outdoor storage exposure.
- Grip and visibility: Handles in bright colors or rubber coatings help with quick installation and safe removal.
- Security vs. convenience: Locks add security for parked trailers; simple pins are quicker for routine towing.
- Compatibility: Check your hitch type (receiver size, latch style) and chain/clip requirements for safe use.
- Maintenance: Inspect pins for bending, wear, or corrosion; replace as needed to maintain towing safety.
Frequently Asked Questions
- What is a swing tongue pin used for on boat trailers? It secures the coupler or tongue area and may be combined with a lock for security when the trailer is parked.
