Stubby Pull Ring - Locking Nose Retractable Plunger without Nylon Patch
JBF National’s stubby pull ring locking nose retractable plunger comes available in 12L15 zinc plated steel, 303 stainless steel, 316 Stainless Steel, and brass. Due to its truncated design, this retractable plunger (also known as an indexing plunger) style lends itself especially well to limited space situations and the flexibility of the pull ring allows for upward and downward movement to make folding away the pull ring as needed, no problem as all. A simple pull and twist of the pull ring engages the locking element, thereby holding the plunger in the retracted position until disengaged by a reverse twist. This retractable plunger also features a radiused Delrin nose for maximum hole engagement. Designed and tested to withstand side loading.
