Keyhole slots provide a great way to hang small cabinets and other projects. A pair of keyhole slots are also often integrated into commercial power strips and other accessories for mounting purposes. The problem with paired slots is that the screws must be laid out precisely on center to work, and misalignment can be hard to correct. I’ve found that commercially available dowel centers do the trick nicely. Just insert the appropriately sized dowel center into each keyhole slot, and then press the item to be mounted in place. Voila! You now have perfectly located centerpoints for your mounting screws.
