The Yak Attack Screwball 1.5 in. Ball with MightyBolts is compatible with the Wilderness Systems SlideTrax Accessory System as well as other track systems.
Simple solution for providing a mounting point for rod tubes on tracks or Mighty Mounts.
I used the 1.5 in. screwball with the 1.5 in. Ram Mount to mount my Lowrance Elite 5 HDI to a 16" Gear Trac on my Hobie Pro Angler 12. Works great!!!! I couldn't be happier with the setup. Its very sturdy and completely adjustable. I submitted a photo so you can see what it looks like.
