Fixing is by two tabs on each side of the product as shown in the photo. The set of nuts for mounting are provided.
A small ledge for something that once put it can not move or to avoid accidental fall on the product side is noted.
Small precision side dimensions that are slightly incorrect on the product description.
Width: 17.5cm
Length: 44cm (excluding feet, with this is 48 cm)
Height: 4.5 cm
Another clarification I received the product with a little shock that a deformed legs. I put more and because the carrier but Amazon packaging reinforcement of this side is a plus. Tweezers to correct the problem and as it is solid all the stars without worries.
A nice product that is in the price although a little bit expensive but the quality is there.
