This Snapmatic module by Systematic Tools is designed to hold the Anex 397 ratcheting driver. The Anex rachet is perfect for use with long 100mm (4") bits and has a smooth ratcheting mechanism and solid lock up that feels almost as good as the Wiha Centrofix. Around back, there are slots to hold the 711L extension, swivel head rachet, tweezers, and spirit level. The modules use powerful rare earth magnets to connect them together with a snap.

The module is designed to hold these tools:

• Anex 397 ratcheting driver
• 711L flex 1/4" hex rachet with extension 
• Uncle Bill's sliver gripper tweezers 
• Spirit level 10x10x29mm 

Best paired with the long bit module.

Instructions for connector magnet and strike plate

• Source parts:
  • (1x) 60x10x3mm N52 magnet for side connector from JC Magnetics
  • (1x) 60x14x1mm strike plates from TotalElement
• Use 60-80 grit sandpaper to rough up surface deeply for glued sides (4-6 passes in two directions)
• Wipe surfaces with Acetone to clean
• Apply even surface of gel-style CA glue to pockets
• Place magnet or strike plate into pocket, clamp for 5 minutes
• Release clamp and allow it to cure for 24 hours before using

If friction fit it loose on rachet or extender, apply a tiny bit of blue tack to add friction. A little goes a long way.
