This pull knob retractable plunger (also known as an indexing plunger) is made completely from the highest quality stainless steel. The completely stainless design ensures corrosion protection which makes these plungers perfect for sensitive areas such as food production and handling. On locking models a simple 90 degree twist engages the locking element, thereby holding the plunger in the retracted position until disengaged by a reverse twist. We offer both locking and non-locking models, and these plungers have been designed and tested to withstand side loading.
