Key Stock

Key stocks from Action Industries ensure a door is safely stopped in its tracks. A key stock is a small piece of metal that inserts between a roll up door’s shaft (or torsion bar that winds the torsion springs on overhead doors) and a pulley gear, sprocket, or other garage door opener. It creates torque and prevents movement by fitting into pre-cut slots known as the key seat and the keyway. By sliding directly into an essential component of the doors lifting mechanism, key stocks guarantee that your door will physically be unable to move when you don’t want it to. Key stocks work on overhead doors, rolling steel doors, and any door with a rotating power device.
