Loaded with multiple neodymium magnets in the base to provide maximum grip inside your toolbox drawer, which has an added benefit of using the magnetic pull force to hold both the blok in place and Wrenches down to the base.  
 
There is also a magnet encased in the vertical wall that holds the wrench up against the blok from both sides.
 
Magnets are encased in the base so they will never fall out or need to be glued in.
 
Priced per blok so you can order exactly and only what you need.  
 
Note:  We recommend removing the drawer liner to give the Bloks to strongest bond in your drawer possible.
