Short double arms on this specialized Slatwall Utility Hook are sized just right for merchandising the target item, a gleaming Trumpet. Close inspection shows the arms are also angled for the product, as well as padded to avoid scratching an expensive product. Trumpet mouthpieces are removed when retiring the instrument from play, but for merchandising purposes I would have left it in place to help project the image an instrument ready and eager to sound off. CLICK thumbnail to concentrate on the hook.
