The gauge of the aluminum needs to be thicker. It does what it says it will do, but very thin strip. Don’t tighten the screws too far or they press/punch through. The strip being thicker would also help with keeping a straight run.

Nice anti-slip covers
These are really nice! They gave my stairs some style plus we now have grip. No more slipping. It is important to follow the instructions, especially about the screws. They work nicely.
