Attach Ikea Faktum FA750 strip above the microwave

I have a Faktum FA750 (60x233cm) with a stacked Snabb microwave (top) and Raffinerad oven (bottom). Above the microwave, you have to insert a strip that must be cut to size beforehand according to the instructions on page 14ff.

Unfortunately, it does not say how to attach it. How would you do it? The use of the normally usual clamp holders does not work because the strip is too narrow and there is no pin hole at the height of the strip.

Mounting brackets screws, be careful you need to pre-drill the strip so it doesn't crack when screwing.

Better

Mirror adhesive tape, with that you immediately have the right distance to the carcass, doors never lie tightly either.
