HJC HJ-29 Base Plate Kit
- Works with HJC RPHA 90 and RPHA 90s helmets
- Includes two base plates (one for each side) and screws
- Buy replacement base plates when your old base plates don’t give good ratcheting action for your shield or if your old base plates get broken
Here is a link to HJC’s website where you’ll find information on installing and removing shields, base plates, cheek pads, chin curtains, etc, as well as helmet care and cleaning.
