Positioning Rings for Dimple Locks

In each case set, one or two positioning rings are included. Depending on the type of set purchased, it will contain a positioning ring for dimple locks and/or a positioning ring for disc tumbler-/detainer locks. The rings, in combination with the corresponding scale, give you a reference point in which range you are with the opening tool (pick or disc setter). In addition, with the positioning ring for dimple pin tumbler locks, you have the option of using a latching function. However, this only works in combination with the grid scale.
