ExacTac Maker Dillon Bruno was fed up with how long it took him to hang three pictures in a straight, evenly spaced line—and get each one hung perfectly straight, too. A few mistake holes and a hammered thumb led him to brainstorm a better method, and it took four years to bring this handy hanging helper to life.

The picture hanging tool makes the job pretty straightforward. It’s compatible with different types of hanging hardware, like sawtooth and D-rings, and it has a built-in level that lets you know when things are straight. Best of all? It eliminates the need for measuring and the potential for “oops” misplaced holes.
