CLEAR "SEE THRU" MORTISE CYLINDER - for Educational Visual Aid and Use as Practice Lock
Adding to our line of transparent practice locks, we are happy to offer this perfectly clear acrylic 5-pinned mortise cylinder to our selection. Comes with 2 working keys. This lock cylinder conforms to the standard mortise cylinder diameter, though it lacks a face plate (this does not effect its usefulness in any way). It fits in our new LockSport Stand as well as the Universal Practice Lock Stand. Hobbyists will enjoy this lock as will serious locksmith students. In addition, it would make a fantastic novelty gift for anyone who loves unique and captivating objects.
Get all three! Choose to purchase all of the transparent practice locks pictured below -- just select option 2 (to the right of the main photo above) when you add to cart.
