The patent-pending Magnemount Cable/Cable Tray Holding System provides a non-penetrating solution to securely carry cables across and down the curvatures of steel water tanks. The high-capacity magnetic solution presents no damage to water tank surfaces, requires no maintenance and can be removed easily. The cable tray’s independently mounted magnets allow it to be placed on water towers or legs as small as 4 ft. in diameter. Magnets are adjustable for easy installation and adjustments.
