Srup pack of 2 trailer hitch plug locks (50 mm) – 4 keys
These trailer hitch plug locks are a simple, effective way to stop opportunist theft of trailers and towbar storage boxes. They’re built for everyday use — reassuringly solid without being awkward to handle — so they’re ideal if you leave a trailer or bike rack on the car overnight or pop into town for a quick shop.
Built for weather and security
The bodies are made from sturdy copper with a silver finish, so they shrug off the rain and won’t rust straight away — a proper bonus in winter. Precision-engineered lock cylinders make tampering harder and give dependable protection when it matters. Each lock comes with two keys, so stick one on your keyring and keep a spare somewhere safe.
Practical fit and compatibility
These plug locks are designed for 50 mm steel couplings and fit many common hitch makes such as Maypole, Daxara and Earth. They’re great for towbars and small storage boxes that use a plug-style lock. If you’re unsure about the fit, measure your coupling diameter first to avoid any disappointment.
- Easy to use – push in, turn the key and the lock is secure; quick to remove when you’re ready to hitch up
- Two locks in the pack give protection for both towbar and a storage box, or a spare for a second vehicle
- Lightweight and compact – stores neatly in the glovebox or towball cover
- Visible deterrent that can put off casual thieves and reduce the chance of opportunist theft
