    Locating Pin Up

    Drill a hole in sheet metal that aligns with an existing hole in another piece. These guides line up with the original hole so you know where to drill. Also known as strap duplicators.
    Locating Pin Down—The most common guides. Use these when sheet metal pieces aren’t attached or can be pried apart.
    Locating Pin Up—Use these guides when two panels are held tightly together and you can’t get beneath the sheet with a drill.
