Ladder Brackets, Locking (Bamford S33)

Do you lie awake at night, frozen with fear of your ladder being stolen?
Well, you're not alone. It's a much more common problem than you may think.
But... fear not! There is a solution!

Lockable Ladder brackets!!
Only one can be locked, but that should be plenty, no?

They're unused other than me putting them on the wall, finding that they're too small for my ladder and taking them off again. Grrrrr.
My ladder is a 3-section ladder and it can _just_ about fit but is a bit of a pain in the bum to lock up. Should be fine for a 2-section ladder.
The _internal_ dims are 155mm x 220mm.

They're a bit scratched from kicking around my garage for a while, but they could be repainted to hide the scratches.
And they don't have to be black. They could be, say, Teal, or Burnt Umber, or even Elephants Breath.

Now, do yourself a favour, install theses and once again you can be sleeping like a babe on valium.
