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.
Install easy, very easy to slide back and forth.
Nowhere in the description did I see that this was a piece of plastic junk. I would never trust a plastic ball to hold my $1400 fly rods and reels. This was the first time I had ever seen a RAM ball that was not aluminum. It should have been identified as plastic in the description and then I would not have bought two of them to throw out.
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.
I installed this immediately and as always pleased as can be with the quality of yakattack products. Thank you.
