Had unfortunately not seen that it is "Plastichrome" and not metal (at the price !!), otherwise I would not order it. And this thing is not even finished "chrome-plated". Miserable!
Cheap plastic product, fastening absolutely unsuitable. Adhesive strips do not stick because the recess provided for the adhesive strip completely disappears. The mounting holes are concealed so that a screwdriver or cordless screwdriver can not be attached cleanly. Why still dowels are supplied knows probably only the manufacturer. I can only advise against the purchase.
