Installed a couple of Argos items last week. When I say installed, I mean hung on the wall.
First was a large mirror. Two 'upside down keyhole' brackets with a recess behind them. Simple. Measure the distance between them, divide by 2, mark centre line on wall, draw horizontal line, drill 2 accurate holes.
This method of fixing is generally a PITA because you have to get the holes 100% spot on - there is no adjustment or 'play'.
Distance between fixing centres? 91.5cm. Divide by 2 = 47.75cm! FFS why not just make it 92 cm? Or 90cm?
Next practical joke by Argos - No:8 gauge/4mm screw (surely the most common screw size used?) won't fit the 'kin hole! I've been caught like this before so I tried it first. Had to use No:6 screws - great for a heavy mirror.
Next item was a coat rack with shelf above. Same 'upside down keyhole' brackets, same problems.
Got that on the wall, slight 'tug' to make sure its secure - and it came off in my hands.
The 'upside down keyhole' brackets were secured to the wooden coat rack with 2 x No:4 x 3/8" screws. To hold three coats FFS!
Replaced with some 'proper' screws & jobs a good 'un.
Do the idiots who design this s**te ever actually try fixing one to a wall?
Or is it all a plot to annoy handymen?
