Installing a protector on a Nox padel racket is very simple. First, take the protector and remove the backing that covers the adhesive. Once you've done this, position the protector on the frame of the racket, ensuring it is at the same height on both sides of the head and aligned correctly with the frame. Once aligned, proceed to stick it from one end to the other, slowly to avoid any bubbles. With this, the protector will be properly installed.
