This sale is for one replacement inner endcap for the Bowflex Selecttech Dumbbells. This inner endcap will only work on the Nautilus/Bowflex Series 1 (will not work on Series 2) of the 552 model and is an original authentic Bowflex product. It has normal wear but no damage and fully functional.

If your dial is spinning around freely this will be the part you need to get that fixed. There is a small tab on the inside of this that connects with the metal disc keeping the dial from spinning (see second pic). If that tab is broken off or worn down it will need to be replaced.

Please note - there are two different types of these endcaps that came on both the Nautilus dumbbells and the Bowflex Series 1 dumbbells. One has a built in piece that the screws from the tab/guard screw into. This specific one does not so it will require both a screw and nut in order to attach the tab/guard.
