For sale is a NEW, Hyster Forklift Safe-T-Lock Model STL1000. 12-120V DC. What you see is what you get. I got this from a Hyster Forlift Parts Dealer in a large box with many other things. This looks brand new to me. However, I cannot test it. If you get it, and it doesn't work. You can return it. You would just pay ALL shipping. Thanks.
