These 2 x 3" magnetic C-channel cardholders deliver a clean, repositionable labeling solution for metal racks and shelving. Constructed from 0.060" thick magnetic material in black, each cardholder mounts directly to ferrous metal surfaces without adhesive, fasteners, or surface preparation, and can be relocated as inventory layouts change.

Warehouse pick lines, distribution center bin walls, manufacturing parts storage, and retail stockrooms are all well-suited applications. The rigid channel profile accepts standard label inserts and keeps them flat and legible in high-traffic rack environments, supporting quick identification of bin contents, part numbers, location codes, and SKUs.

White label inserts are included with each case of 25, compatible with printed or handwritten labels. The parcel-friendly format makes restocking practical for facilities that rotate or expand rack labeling systems on an ongoing basis.
