These 3 x 8 inch black magnetic C-channel cardholders offer an adhesive-free method for mounting location labels, SKU cards, and identification inserts on metal racks and shelving. The .060 inch thick magnetic backing delivers firm, repositionable adhesion on ferrous surfaces with no tools required for installation or relocation.

Warehouses, distribution centers, manufacturing facilities, retail stockrooms, and office storage areas all benefit from the quick-swap C-channel slot design, which allows inserts to be changed in seconds as inventory locations or labeling schemes evolve — a measurable advantage in high-turnover pick environments.

Each case contains 25 cardholders in black with white paper card inserts included, ready for immediate use upon receipt. The consistent black housing maintains a professional appearance across mixed racking and shelving systems. Ships via parcel carrier.
