Garmin Striker Ram mount (1" diameter ball joint)

This is used on my Hobie Sport to mount my Garmin Striker 4 to a T-slotted rail I've customized for my Hobie. The T-slotted rails can be purchase at the site referenced below:

Part 1-1 is the base mount with a 1" diameter ball joint. You will need to use a 1/4-20 Threaded tap to tap the center hole for use with threads. I use a 1/4-20 socket head screw from Mcmaster Carr for mounting to the rail:
