JBF National's l-handle locking nose retractable plunger comes available in steel, 303 stainless steel, and 316 stainless steel. The l-handle features 360 degree rotation which allows for maximum l-handle positioning flexibility. A simple pull and twist of the l-handle engages the locking element, thereby holding the plunger in the retracted position until disengaged by a reverse twist. This retractable plunger (also known as an indexing plunger) also features a nylon thread coating to ensure ultimate thread locking in heavy vibration situations.
