  • Publication number: 20190336983
    Abstract: A tiered magnet modular collar designed to catch metallic objects inside a garbage disposal. The tiered magnet modular collar includes a plurality of tiered magnets, each tiered magnet having a first elongated member offset from a second elongated member. The first elongated member is atop a second elongated member via a connecting bar. The first elongated member has a first distal end opposite a first proximal end with a first interior surface opposite a first exterior surface. The second elongated member has a second distal end opposite a second proximal end with a second interior surface opposite a second exterior surface. The first elongated member and second elongated member have an arcuate shape such that the tiered magnets affix to one another in an annular manner. In this way, a user is able to affix the tiered magnet modular collar around a garbage disposal to catch metallic objects inserted therein.
