Difference between U/D shackle/lock?

Hello

(If this is not the suitable section in the forum to ask a lock-related question, please point me in the right direction or move the thread there)

After getting my commuter bike stolen, I'm looking for really secure U locks and was told to check the Sold Secure site that tests products in the UK.

I currently use a folding Abus Bordo Granit X-Plus 6500 and learned how to lock it securely (not leaving space between the wheel/frame and a fixed point), but I'd like to also get a U lock when I need to leave my bike outside until late at night (which was when it got stolen, in a quite lively area).

For "Bicycle Gold" items, they have "D Shackle", "U Shackle", and "U Lock", and they all look the same.

Would I be correct in understanding that "D Shackle" is really the tiny one that you should as a lock with a heavy duty chain, while U Shackle and U Lock are synonyms?

Thank you.

U is open D is closed ..
Tire/Tyre, center/centre, Aluminum/aluminium ,, Might just be different versions of the same ,
like the language.

Get more than one lock, and if they require greatly different tools to defeat then that is better.

Thanks, but they use all three expressions on the same site :-/

I guess they're the same, and small D/U shackles are just meant to be used with a big fat chain.
