This is an ABS safety wire holder that magnetically attaches to your toolbox. I've designed three versions: a single, double and triple spool holder. Each holder can secure the magnets via lock nuts or heat inserts. I've included a list of hardware that both styles require to assemble. Once the magnets are installed, I recommend cutting a strip of 4" wide erosion tape to cover the back side. This helps prevent the holder from sliding and adds a layer of protection between the magnets and your toolbox.

Lock Nut Hardware:

-M4-0.7 x 16mm Countersunk Bolts

-M4-.07 Lock Nuts

-100lbs (Pull Force) Neodymium Magnets

Heat Insert Hardware:

-M4-0.7 x 12mm Countersunk Bolts

-Heat Inserts (M4 x D6 x L6)

-100lbs (Pull Force) Neodymium Magnets

Note: I bought all the hardware and magnets to assemble this project on Amazon.
