This is a standard 65mm (TF-65) thermoforming fixture with side bolt (SHCS). Once your socket is pulled you grind up to the bolt, remove it, and continue with your normal fabrication.  This makes great way to fabricate the hole for your BULLDOG shuttle lock push button. It can also be made so hole aligns with the BULLDOG shuttle lock of your choice.

Previously purchased TF-65 dummies can be modified for an additional $30.00
