Uneven wall + Elfa track?

[jonasnjonasn]

Hello! I set up a small Elfa system consisting of two rail tracks. Then it will have two 70cm long shelves and a desk top.

When I was about to screw in the last screw, I noticed that the rail sticks out a bit from the wall because the wall is uneven. So the screw does not fasten properly. Also, that particular hole became a bit large, and I used PL400, so the screw and plug move. What should I do now? Just leave it and assume the remaining five screws and plugs will hold, or address the last hole somehow?

What kind of wall construction is it?

 

[jonasnjonasn]

Lightweight concrete!

Do you have 5 screws/plugs in each rail? What is the dimension of the screws?

 

[jonasnjonasn]

Three on each rail. So a total of six, but one that doesn't fit well.

Diameter: 5.5 mm
Length: 64 mm

There shouldn't be anything very heavy on the shelves at the top. The shelves are 70 wide.

Place a spacer to fill the gap and see if you can get the screw to engage a bit.

Good idea. Maybe a piece of wood will work?
Or I'll have to find a larger plug and screw and see if that helps.
Although everything might hold up well regardless. It feels like the rails are fixed.

Good idea. Maybe a wooden piece would work?
Or I could find a thicker plug and screw and see if that helps.
Although everything might be supported well regardless. It feels like the rails are secure.

I would probably do both. There is also lightweight concrete screw that usually works very well. You screw them in without a plug. You drill a guide hole and then screw the screw in without a plug. You'll need to experiment a bit.

Ah thanks. Considering some anchor mass as well.
