Magnetic cabinet latches are available from the Woodworkers Store catalog, 4365 Willow Drive, Medina, MN 55340, (1-800-279-4441) and at 14 company stores throughout the U.S. They're on page 50, item #63164 for the lock ($5.25./$4.74 for 4 or more) and item #63172 for the magnetic key ($5.95 ea.),one key activates all locks. The lock is fully concealed inside the door, has a template to mark the installation location, and installs with a screwdriver. It works on doors 1/2" to 1 1/4" thick. There may be similar locks other places, but this is the first one I found in my catalog. [Posted in FML issue 1743]
