The brackets themselves are of excellent quality, with the ability to use a padlock on each bracket. However, when fitting these to my house wall, I had trouble because the screws were too big for the wall plug. The instructions didn't specify which drill bit to use, so I tried a 6mm bit (too small) and then a 7mm bit. The wall plug fit loosely(ish) in the 7mm hole, and yet I couldn't get the screw in all the way. In the end, I tightened it up as much as I could (it's not going anywhere!) but the brackets are a little loose. With the ladder on, and the fact that it won't be disturbed very often, I think it's just about acceptable, but nonetheless, the fittings could've been so much better.
