Maypole universal trailer hitch lock for 50 mm couplings
Simple, practical protection for trailers that use the common 50 mm coupling. The Maypole hitch lock puts a clear, physical barrier across the hitch so someone can’t just unbolt or hitch up your trailer and drive off. It’s straightforward to use — which is exactly what you want when you’re out and about.
what it does
The lock fits most pressed-steel and cast 50 mm couplings and uses a case-hardened 12 mm steel bar to block the hitch. That prevents the drawbar from being latched or towed away easily — a no-nonsense deterrent to so-called ‘towaway’ theft. Its bright, obvious appearance also helps put off opportunist thieves before they even try their luck.
key features and benefits
- Durable protection: case-hardened 12 mm steel bar resists cutting and brute-force attacks.
- Secure lock: high-security, anti-pick mechanism — supplied with two keys so you’ve always got a spare.
- Visible deterrent: when fitted it’s immediately obvious the trailer is secured, making it far less attractive to thieves.
- Easy to handle: compact and relatively lightweight for a metal lock — manufacturer lists ≈500 g (some sources show ≈1 kg); either way it’s easy to carry and fit.
- Flexible fitting: designed for standard 50 mm couplings (pressed-steel and cast). Not suitable for stabiliser-type couplings; on some couplings you may need to fit the lock in a different orientation to sit correctly.
typical use cases
Great for leaving a trailer on the drive or parked overnight, making short stops on jobs, or when you’ve left tools or kit inside. Works well for general utility trailers, small plant trailers and box trailers that use standard 50 mm couplings. If your coupling is a stabiliser or has odd geometry, double-check compatibility before buying.
quick installation tips
- Check the coupling type first — this is made for standard 50 mm couplings, not stabiliser couplings.
- If it won’t sit straight away, try rotating the lock — some pressed-steel couplings need a different orientation to line up.
- Keep the spare key somewhere safe — two keys are supplied and it’s handy to have a backup.

Will this stop a determined thief? Nobody’s saying any single device is foolproof, but this lock removes the easy option of towing the trailer away and makes your trailer a far less tempting target. If you want extra peace of mind, use it alongside wheel clamps, CCTV or other measures for layered security. In short: a sensible, low-fuss way to make your trailer a lot less likely to be nicked.
