Indexing plungers are used where any change in locking position due to lateral forces should be prevented. A new indexed position can be only be moved to after the pin has been manually retracted.
In addition to manual operation, the key ring also enables the connection of elements for remote operation, such as a tether cable.
Form X and Y are recommended for applications where the indexing pin should remain disengaged for an extended period and be prevented from springing back.
