Garvin Industries’ magneticcable support clips can be used on metal surfaces including steel beams, purlins, ceiling deck and drop-ceiling channel. The company says the magnet’s strength ensures the supported cable will not dislodge over time, and that magnetic flux will not interfere with wires and cables.
Shown on this page with black clips, the device is also available with white clips and with cable rings of one-half-inch, three-fourths-inch, and one-inch.
