12mm x 3mm x 5mm Countersunk Neodymium Ring

We supply two styles of neodymium magnets – the flat disk or a countersunk ring.
The flat disks are ideal for using on traps with a thin metal door that falls down when sprung. These magnets have a strong, self-adhesive, 3M VHB backing.
The countersunk rings can be screwed or glued to a surface. We have used these on Doc 200 traps.
