If you are tight on track space, the DoubleHeader includes an additional feature to add LockNLoad accessories like YakAttack rod holders, camera mounts, and more. Simply replace the stock knob and MightyBolt from the DoubleHeader with the LockNLoad base of a rod holder or other accessories, and you are able to have multiple attachments on a short section of track or a single point of attachment like a MightyMount II. The DoubleHeader track mount is compatible with YakAttack GearTrac, MightMount XL, MightyMount Switch, MightyMount II, and most other factory-installed kayak track.
