Knurled Knob - Locking Nose Retractable Plunger without Nylon Patch
JBF National’s knurled knob locking nose retractable plunger comes available in steel, 303 stainless steel, 316 stainless steel, and brass. A simple 90 degree twist engages the locking element, thereby holding the plunger in the retracted position until disengaged by a reverse twist, and the knurled rim allows for maximum grip regardless of grip situation.
