Trimax T2 premium 1/2in keyed receiver locking pin
If you’re after a solid, no-nonsense locking pin to keep a ball mount, bike carrier or trailer accessory exactly where it should be, the Trimax T2 is built for the job. It’s a straightforward mechanical lock that puts off opportunist thieves and gives you proper peace of mind when gear’s left on the back of the vehicle. Tough finish, simple operation and robust internals mean less faffing about and more time on the road.
Built for real-world towing
The T2 uses a hardened steel, double-headed—often called a “dog bone”—design with a triple-plated chrome finish to resist corrosion and everyday wear. Its patented dual lock lug arrangement offers excellent pull strength, and the 1/4-turn keyed action locks and unlocks quickly without fiddly springs that can seize up. That’s a proper advantage if the pin gets wet or spends months outside.
Practical features you’ll notice
- The O-ring and rubber protective cap keep water, muck and road salt out of the keyway, so the lock keeps working year after year.
- Includes two Type A spring-loaded 7-pin high-security keys — tough keys that resist bending and make drill-outs harder for would-be thieves.
- Double-headed design leaves a 2-1/2in gap between the heads, suitable for most accessories that take a 1/2in pin.
- Simple 1/4-turn locking mechanism that can’t be false locked — quick to use and reliably secure.
Where it fits and what it does
This is a 1/2in diameter receiver pin, commonly used with Class II receiver hitches (1-1/4in receptacles). Typical uses include securing ball mounts, drawbars, accessory carriers or ornamental receiver plugs. If you’re unsure whether a 1/2in pin is the right size, check the diameter of the hole in your accessory or the hitch receiver description before you buy.
Technical notes and everyday concerns
The item weighs roughly 360 g and ships as model T2. No batteries are required — it’s entirely mechanical. A quick heads-up about load ratings: the T2 is designed for locking and theft deterrence rather than serving as the structural, load-bearing element of a tow assembly, so always follow the towing load instructions from your hitch and accessory manufacturers. Also bear in mind that international versions may vary slightly in packaging or instructions.
Why choose this over a cheap knockoff?
Trimax has honed this design over the years with an eye on durability and real-world security. The high-security key, hardened steel components and extra corrosion protection mean it lasts longer and copes better in wet, salty or muddy conditions. No faff setting it up, no batteries to worry about, and the protective cap keeps the keyway clean — less maintenance and fewer nasty surprises.
If you want a straightforward, high-quality receiver locking pin to deter theft and keep accessories secure, the Trimax T2 is a sensible, long-lasting choice.
