The bar is aesthetic, while brushed aluminum, except for the two ends in black plastic, which include the ability to set the bar to the wall (screws included), but which are very discrete.
It is also one of the few bars without visible screws; recent impair the aesthetics, but also prevent any fastening means other than screws. With this toolbar, you can use double sided tape (real, to fix mirrors or heavy loads on the walls) and thus avoid piercing your kitchen splashbacks. Mine is made of glass, it is always difficult to break through and fragile.
The bar is available in 30 cm or 45 cm; this is the model that appears on the photo and that seems just as great for a 30 cm; 30 cm allows to cram 6 max knives; which allows to adapt to many configurations and needs.
