Ready At Hand Gun Magnets are made with powerful Rare Earth Neodymuim Magnets that lose 1% or less of their magnetism every 10 years. Ready At Hand Gun Magnet, LLC took into consideration the design flaws made by our competitors. Our magnets are enclosed in a pvc casing with 2 recessed holes for mounting and a soft vinyl pad. The recessed holes ensure that your gun does not come into contact with the mounting hardware. There are no gromets that will rust. Mount a Ready At Hand Gun Magnet on a surface and each magnet will hold up to 10 pounds of balanced gun weight.
