A latch for use with a plug-in unit may comprise a head, a rigid body, a pin, and a lever. The head may be configured to retain the plug-in unit within a chassis associated with a rack system. The rigid body may extend from the head and be configured to interface with a user's fingers. The pin may extend transversely from both sides of the head into a case associated with the plug-in unit and be configured so that the head and the rigid body rotate around the pin as a single body when the rigid body is pulled by the user's fingers. The lever may extend from the rigid body and include a detent configured to engage the chassis. The detent may be configured to restrict the head and the rigid body from rotating around the pin when the detent is engaged with the chassis. The lever may be operable to release the detent from the chassis. The head, the rigid body, the lever, and the detent are manufactured as a single unitary body.
