Why the 7×4 galvanised box trailer is built differently
The Xtra Secure range is aimed at people who leave a trailer loaded, often overnight and often somewhere they can’t keep an eye on it. The body is clad in chequer plate rather than just composite panels, and a fitted padlock box shrouds the padlock so it can’t easily be attacked with bolt croppers. It’s the same galvanised chassis and phenolic-topped steel floor as the rest of the Cube family underneath.
That extra protection adds a little weight compared with a standard Cube, so it’s worth checking your car’s towing limit. For most estate cars and SUVs it isn’t an issue.
Who it suits
- Trades who keep tools and materials in the trailer between jobs
- Market traders and event crews storing stock
- Anyone parking a trailer on the street or in a shared yard
- Motorsport and hobby users with expensive kit inside

Every 7×4 galvanised box trailer is backed by our own spare parts stock.
Security tips
No trailer is theft-proof, but layers help. Use the padlock box with a closed-shackle padlock, add a hitch lock and a wheel clamp, and park with the door or ramp against a wall where you can. The GOV.UK guide to towing with a car also covers what you need to know about weights and licences before your first trip.


7×4 galvanised box trailer FAQs
What padlock should I use with the 7×4 galvanised box trailer?
A closed-shackle or disc padlock that fits inside the padlock box gives the best protection, as there’s very little for a cutting tool to grab.
Does the 7×4 galvanised box trailer need a special licence?
No. It’s within the limits most full car licence holders can tow, as long as your vehicle is rated for the weight.
Can I add shelving or ply lining?
Yes. Ply lining and fitted toolboxes are available as extras, and many customers add their own racking inside.
