Durable index plunger design stands up to wear in industrial manufacturing. To augment your pins and center posts, UJEN unveils a pull knob solution with concave, flat, convex, or dotted heads, supplemented by a color ring and color disc each offering 7 color variants. Taiwanese mold and CNC synergy yields high precision and durability; if going green matters, pick plastics with oyster shell or wood fiber. Ergonomically engineered, the knob alleviates repetitive strain, and ISO9001 oversight secures consistent quality. From specialized machinery and sports equipment to aerospace or automotive lines, this pull knob helps B2B customers achieve a more user-friendly, visually appealing multi-position locking experience.
