SOT Stainless Steel Magnet installation driver tool for installing SOT frame and panel magnets.
Just place the correct side of the magnet on the tip of the tool, place a tiny drop of cement (super clue or similar. Gel works best.) on the magnet side that goes into the hole then press the magnet in.
(make sure you have the correct magnet polarity for panels and frame)
 
SOT magnets are:
Frame: Polarity "S" South cement inside, (Black marked side "North" should show out).
Panel: Polarity "N" North cement into the panel, (Black marked side "South" should show out) and connect to the frame.
