Threatblast from the past.

Just installed 4 of these, £15.99 off of an amazon seller.
There's a design flaw whereby the metal is curved around at the top to hold the hook, but in such a way that it holds the flat plate ~5mm off the wall, meaning you can't get a tight fit flat against the wall. This was easily remedied by sliding a piece of 12mm MDF (other woods are available) behind the plate and drilling out the screwholes.
The fixings supplied don't match the photo, and were rubbish anyway with cheap rawlplugs and screws too short, so I substituted much more substantial and deeper ones of my own as we have over an inch thick of crumbly old plaster before the drill hits the brick.
They've yet to fall off the wall so think I must have done something right. And, yes, I'm aware that to get the bike on the right out the other 3 have to come out first, however they're hung in order of how infrequently they get used.
Fortunately we're blessed with a substantial if amusingly hexagonal box room to accommodate the bikes and an array of shelves above to ceiling hight.
