Security ground anchor

[NeiljohnUK]

Cordless grinders however are cheap, and effective, so as many locking points and separate chains as possible are required. My favoured ground anchor design uses thick wall box 2" section steel, cut at 45 degrees to make it safer to roll a vehicle over, long enough for 2 or 3 rawl anchors (bolt type) that are tightened through 1" holes through the top, pass the chain through and you can't undo the bolts. Cheap and reasonably effective for most things, multiplied to delay thieves so they have to cut several chains, then U locks, then difficult to access padlocks on the cast spokes of my road bikes. Such are the joys of living in an English town these days...
