This tool holder has several magnets or pieces glued into a regular rail rather than a continuous length, with some sort of adhesive coating on top to give it a premium look. it's all a length of magnetic material. The magnetic holding power of the magnets and this stand is also noticeably less than some others I've cost more. However, the price is half that of others with higher holding power, so all in all they're pretty good value for money. In terms of mounting, it's almost identical to the more expensive items, but you also get some plastic mounting spacers to help you align and place them in line, and to create clearance from the mounting surface for items that shape closer placement not favored. surface mount.
