What Are Push Knob Detent Pins?

Push Knob Detent Pins are a type of quick release pin designed for secure yet removable installation. The pull ring serves as an anchor point for a retaining chain and offers a secondary removal method in place of the flange. Manufactured from A2 stainless steel, these detent pins are corrosion resistant and ideal for heavy use environments where reliability and speed are critical.
