* To lock an attachment and avoid it to be detached when you load an outfit that does not contain it * To wear or detach items

Good to know * Enabling RLV on your viewer does not expose you to actions from others until you wear some RLV device * Only objects you are wearing can send RLV commands * RLV can not access your L$ account. * When RLV is active you can always check what attachment is doing what in your RLVa menu under Restrictions
