Crimp Die Adapter - use only with Tecre Model #100. (black machine, red handle).
This adaptor is placed in the crimp die only when making 1" round plastic back buttons. If the machine is needed to make collet buttons, simply remove the adapter.
This is a replacement part. When you order a new machine from Tecre, this part should be inside of your sample packet of buttons that came inside of the machine box.
