What Is It?
A subscriber sent in three photos of a key-operated lock and asked what it was used for. At first it looked like a lock for a display cabinet but upon further inspection the label contained the wording "Superior Interlock." That solved the riddle.
Interlocks are a safety feature often used on large factory machinery. If a maintenance person must enter the machinery or work close to moving parts, an interlock is used to prevent someone from starting the machinery. Some interlocks contain several lock cylinders so more than one person must be present to set the interlock into an unlocked position.
An alternative is a hasp made by Master Lock. The hasp contains slots for several padlocks. All of the padlocks must be removed before the hasp can be unlocked.
