On our 2015 Newport, there is a spring loaded handle on the fwd edge side with 2 holes for the handle pin for extension adjustment. However ours came with 2 wood screws hidden under the most outboard edge of the table fastened by the factory -(for shipping?) making the adjustment inoperable. Its been removed and now extendable. Just remember to track in table and leaf when closing slide. I can now use 4 chairs somewhat comfortably
