A totally flat backplate and glue-on receiver make this Plastic Hook slide-in straight entry. The adhesive mount means it can be put in play on a number of surfaces, and I assume, make it a good choice for short-run point-of-purchase display needs. With a jig, you could get repeatable hook locations at whatever interval you needed. The straight-entry characteristic is an advantage in tight merchandise layouts like jewelry small item merchandising as here. Note, however, that hook placement is staggered to allow offset placement of dangling and elongated items. CLICK the thumbnail for a closeup of the hook alone.
