Discounted Ground Anchors @ Screwfix - £3 and £4

[G]

Down from £16 for the £4 one - not going to amazing I'm sure, but a good price for a ready to go kit, albeit a very basic one, maybe even useful to have for 'guests' etc.

I wonder if the smaller one would fit under the larger one so that you could get a double skin effect.

They are listed by width, so I expect the bolt spacing will be different, but overlapping.

You could drill the smaller one to also expect the larger one bolted-through, but then might realise likely how easy it is to cut them and give up .

You could always just put two side by side instead - but if you're going to this hassle, there's probably better options!

They're cheap enough to buy a few, stick a cordless drill in a bag and fit them outside the prostitutes flat when you're in the dodgy areas of town and can't find anything to lock your bike to.
