This little gadget is a double-sided stretchy-belt tool that is used for safely removing and installing stretchy drive/alternator and accessory belts without causing damage to either the belt or the pulley.
Just introduced by Laser Tools (part number 8331), this is a combination of removal and installation tool for most stretchy-belt applications. On the face of each side of the tool is a magnet to keep it in position as the pulley is turned to remove or install a new belt. As you rotate the crankshaft or pulley (by hand with a ratchet), the belt is eased steadily over the edge of the pulley. A robust and solid tool, it is zinc-plated for years of use.
