A Better Square-Drive Knob

Get a solid grip on that bottle with a Pro-Werks Bottle Knob. This lightweight, all-American solution features deep notches, and they match the rest of the Pro-Werks lineup of signature Easy Turn Fill Caps and aluminum knobs

Starting with American melt, aircraft-grade 6061-T6 aluminum; we precision machine each knob on one of our multi tasking MAZAK CNC machining centers, then finish them in your choice of anodized black or silver and our popular micro-polished aluminum finish.

Available in two different square drive sizes to accommodate valves found on most CO2 bottles. For proper selection, we recommend that remove your original knob and measure the "square drive" of the bottle valve to confirm your size before ordering.


Crafted with pride in Muskegon, Michigan, USA
