DescriptionThe whole story▼
The locking axis is what the OXO's moving parts pivot and latch around, and the fixings that hold it are small enough to disappear during a strip-down. FX8721 replaces them as a complete kit: Shark calls it LOCKING AXIS FIXING KIT, in French KIT FIXATION AXE VERROUILLAGE, black, at 20.33 EUR.

Ordering by part number
Note that the number ends in 1, with no P after it, which is how Shark lists it. On the old bag or in the parts documentation it should appear exactly as FX8721. The SKU for the black version is FX8721BLKTU, the only one listed.
Compatibility
The OXO is the helmet Shark's price list names for FX8721, in the column reserved for the helmet model. We take the fit from there and from nowhere else. If your helmet is not an OXO, this kit is not for it, whatever it looks like.
