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.
Item worked great and as advertised. Great quality. ACK customer service is outstanding and second to none.
Ball works great, especially on the right (starboard) side of the kayak. The better option for the left (port) side is: Item# 14299 - YakAttack HD Track Mount Mounting Plate. This keeps the ball from untwisting/unlocking on the left side, when ever there is pressure from rod when a fish is on the line.
