1/2" adapter for 1/2" round bars. The adapter inserts into the 3/4" bar hole and is secured with the provided two socket screws. The adapter is made from aluminum and protrudes slightly out of the bar hole for easy removal.
Use Instructions: Remove the socket screws from the cutter bar holder. Screw in the socket screws provided with the adapter. They are the proper length to secure your new cutting bar. Screw them until the heads of the screws are flush with the outside of the cutter bar holder. Then insert the adapter with the slot centered on the screws. This allows the screws to clamp onto your cutter bar and not the adapter. Never use the screws to compress the adapter as it will damage the aluminum.
