Zamp FIA Z-20 AntiFog Series Shield Photochromatic

Exclusively from Zamp... Photochromatic Shields
Go from bright to dark racing conditions without having to change shields!
The new Z-20 Photochromatic Shield smoothly transitions from clear to dark smoke (or vice versa) depending on the brightness of the track, without having to change the shield!
One shield works for Night or Day

Tear Off Note: If your tear offs are not allowing the photochromatic to work, it is because the tear off or adhesive is blocking the UV light. Z-Optics Tear Offs do not block UV light, allowing the photochromatic shields to work.

Z-20 Shield Replacement:

NOTE: DO NOT USE power tools or overtighten screws when changing shields.
Step 1 - Lay a towel on a flat surface and set the helmet on it.
Step 2 - Remove the shield pivot tensioners on each side. (This is the smaller screw on the sides of the shield.)
Step 3 - Remove the shield pivot screws on each side. (This is the larger screw on the sides of the shield. For best results, we suggest using a quarter to loosen/tighten these screws.)
Step 4 - Remove the shield. We suggest using a soft cloth towel to wipe down the rubber seal as well as where the shield mounts to the helmet for best results.
Step 5 - Place the new shield on the helmet. There are two white washers that go between the shield and helmet, make sure these are in place before re-installing the shield pivot screws.
Step 6 - Hand thread the shield pivot screws to hold the shield in place. Once hand threaded, use a quarter to tighten until snug with the helmet shell. Do not overtighten.
Step 7 - Hand thread the shield pivot tensioners, then tighten to desired tension for shield movement.
