This device is driving me nuts trying to install it, I'm hoping someone here may have one and can enlighten me.
The brake includes an integral jam nut system similar to the APA Bastard series, except this jam nut is turned counterclockwise against the barrel shoulder. The problem is, once the brake is timed and the jam nut seated on the shoulder, any additional torque used to tighten the device securely cause the brake to spin loosening the entire assembly. The brake has no flat spot to accept a second wrench and, the holes through the ports are too small to accept anything that would be strong enough to serve as a lever.

I have sent a message to the manufacturer, just wanted to see if anyone here can lend some insight.
Thanks
