In 1997 both of my sheds were burgled. I thought I’d made them secure enough. I’d used hasps with the thickest staples I could find on the market (similar to these) and disc padlocks with hardened shackles. But the burglars cut through each staple in two places making a gap through which the padlock shackle could pass. My advisers suggested the burglar used a hydraulic bolt cropper. The burglar cut through steel as thick as a man’s little finger. So I took securing shed doors very seriously and made immediate improvements.
While on the subject of sheds why not take a look at my post about putting a “Radio Controlled Wall Clock In My Shed”. — HC
