Ball bearing whiffle tree.
The whiffle tree is the threaded rod mounted on the bottom of the pop up. A draw bar runs up and down the bar, and pulls or release the cables.
There were two types of whiffle trees used. Ball bearing and plastic delrin nut. This style of ball bearing tree is more commonly found on larger box sized units, and units with power lifts.
Note : The draw bar has an internal caged ball bearing system. Do not run the draw bar off of the whiffle tree, or all the bearing will escape ruining the assembly. Running the draw bar over a hole in a removed stop can also result in failure. Use a high quality grease to lubricate the tree, ideally one that does not attract moisture for colder climates.
