National Mfg N302-315 Ceramic Block Magnet 3 Pack

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N302-315 is a rectangular ceramic block magnet sold in a pack of three. Each magnet measures 1.875 inches x 0.875 inches x 0.375 inches and is gray in color. These ceramic disc magnets are suited for light to medium weight mounting tasks. Adhesive can be applied to the flat back surface to attach the magnet to an object, which can then be placed on any ferrous metal surface. Common surfaces include refrigerators, metal lockers, and whiteboards. Installers, facilities maintenance staff, and general trades workers use these for organizing tools, securing signage, or mounting lightweight components in shops and commercial spaces.

These block magnets are appropriate for both household and light commercial applications. They attach to metal surfaces without mechanical fasteners, making them a quick solution for mounting labels, lightweight fixtures, or organizational accessories. The ceramic construction provides consistent holding force for light to medium weight items and resists demagnetization under normal service conditions. Each pack contains three individual magnets, allowing multiple mounting points per project.

Installation Notes

Surface preparation is recommended before bonding: clean both the magnet back and the item to be mounted with a dry cloth to remove dust and oils. Apply an appropriate adhesive to the flat back face of the magnet and allow full cure time before loading. No special tools or trade certifications are required for installation. Avoid exposing ceramic magnets to sustained impact or high heat, as either can reduce holding strength.
