New Style:

Replacement String Jaw set for any Klipper USA stringing machine from 1993 or later. These jaws will only fit if your machine already has the 3-piece String Jaw system as shown.

Old Style:

Replacement String Jaws set for any Klipper USA stringing machine from 1992 or earlier.  If your machine currently has the 2-piece String Jaw system as shown, you must purchase this style unless you opt to upgrade.  See the paragraph below for information on upgrading.

The New Style jaws greatly increase holding power, eliminating slippage.  The only way a machine with the Old Style String Jaws can be upgraded to the New Style String Jaws is by purchasing the Replacement Rocker Arm Conversion.  The New Style String Jaws will NOT fit on the Old Style Rocker Arm.
