Offering parametric customization, this model allows adjustments in hole size and number of finger holes to suit individual requirements. It functions optimally with 3, 4, or 5 wings, while more can be accommodated by altering radius or finger hole dimensions. The conical hole design ensures easy threading and self-threading onto the rod.
