1 3/16″ high x 1 13/32″ wide x 19/32″ largest body diameter (Actual: 1.200″ high x 1.415″ wide x .600″ largest body diameter). Brass and steel body. Steel shackle. Brass wheels. The lock works like the original, and four wheels must be aligned correctly before the two buttons on either end can be pressed in to release the shackle. There is a trick however. The center knurled body section (which looks like the other two smaller knurled body sections that don’t move) must also be turned to a certain location before the buttons can be pressed in. Once everything is aligned correctly the shackle will be released, and can be removed from the lock. 2009. Only 1 of these locks were made.
