SPK: Slider percussion keys
In addition to the simple percussion keys, there is also the “Slider Percussion Key”, or SPK for short, developed by Multipick.
The “SPK” is the answer to small changes that various cylinder manufacturers have made to make opening with simple percussion keys more difficult. Manufacturers of different brand locks often use the same profile and the same pin spacing as before, but more and more often there are some manufacturing variations. For example, changes in the distance from the front edge of the cylinder to the first pin, pin spring thickness, pin shapes, coupling differences, etc. For experienced users, this is no problem with our conventional impact wrenches. For less experienced users, our SPK wrenches are ideal because they can skillfully eliminate the points mentioned.
