These 1" x 6" magnetic C-channel cardholders deliver an adhesive-free labeling solution for ferrous metal shelving, pallet racks, and bin systems. At .060" thick, the magnetic material holds firmly to metal surfaces without clips, tape, or fasteners, while the channel profile accepts standard card inserts that swap out quickly and without tools.

Warehouses, distribution centers, manufacturing plants, and retail stockrooms rely on these cardholders to keep rack and shelf locations clearly identified. The channel design is especially practical in high-turnover environments where slot assignments change frequently and label updates need to happen fast.

Each cardholder has a black finish for a uniform appearance across installations. White card inserts are included in every case, so units are ready to deploy immediately upon receipt. Cases contain 25 cardholders and ship via parcel carrier.
