FSC ASA Knob

Running HPA through your FSC or T9.1 can be a challenge with the default On/Off knob.

We've designed a simple adaptor for the knob that slips over the existing knob and is held in place by a powerful magnet.

This can give you

- A better grip to more easily and quickly engage the air especially when using gloves or muddy hands.
- Easier to use in the dark, the knob is larger and easier to feel
- The knob has an indicator line so that you can see if the air is already engaged
- The default colour is black and orange
