OXFORD LK402 Oxford TerraForce Ground Anchor. Sold Secure Approved to Motorcycle DIAMOND

This product feels solid and well built. You have to hammer in the transversal bolts but other than that it looks super secure once anchored in concrete. The loop is big enough to get a big chain through. I would definitely recommend. I've used as extra security for my bike shed. This won't be my weakest link.

Had it buried in concrete at the front of the house & gives me a good anchor point to lock up the motorcycle. Very happy so far. Makes me feel like the bike is more secure...

Bought two of these for different positions of parking my motorbike, easy to install with a bag of postcrete. Very happy with how solid they feel in the ground. Side bars are hammered in place to secure

Needed to install a ground anchor to secure equipment. This is a very robust anchor and easy to set into concrete.

We have one of these already and the product is great. What we found very disappointing was that Amazon left it on the doorstep for anyone to take when we had left instructions to leave behind wheelie bin. No point leaving instructions as they are ignored

Concreted this into the ground with postcrete, very solid

Wow, this thing is so sturdy I can't see it ever been removed unless you were one of those road workers with your vibrating hammer to hack it out! I don't think its breakable with a lump hammer or saw. The only thing its vunerable too would be a power grinder and I'm sure I or a neighbor would hear that!

The anchor itself seems to be be fairly sturdy construction and when set in concrete would take some effort to remove. The hoop itself is thick and feels like it would take some cutting without power tools.The downsides are that the hoop itself doesn't rotate in anyway so you need to make sure that when you set it in concrete you have it set right. Correcting it after it's set might be more trouble than it's worth. Also depending what chain you're intending on getting even though the inner hole seems fairly large you may struggle with the larger chains such as the 16mm or 19mm Almax security chains. Apparantly, with a little time and effort, you can grind the inner ring out as it is only off by 2-3mm so once you've removed the powder coating you're almost there without unduely compromising the rest of the hoop. With certain chains it may also be possible to loop round the bottom of the outside of the loop rather than going through the loop itself. This has still to be tested however.The concreated in anchors seem more sturdy to me than those you drill into the floor, but either way nothing will stop the determined (and tooled up) theif. The best you can hope for is enough time for your alarms to wake you up so you can deal with the pesky blighter yourself, I'm sure Amazon do a fine range of baseball bats,obviously not conding violence here, just incase you like sports as well as motorbikes :).
