A Magnetic Brick that attaches to all cast iron and steel weight stacks.The Platmate Brick is designed specifically for selectorized - or stack weight - machines. Build strength steadily with 2.5 pound increments instead of the typical 10 or 15 pound increment.  Microloads are a vital part of successful training, and PlateMates are an ingenious and perfect, practical solution. When the workout's finished, your brick attaches securely to the framework of the machine, so it is always easy to find.
