Frequently asked questions
How often do anti-rotation blades need replacing?
They are a wear part — the edge that grips the cap dulls with use, and a dull blade lets the cap spin instead of tightening, so most lines keep spares on hand.
Does the blade fit any capping head?
The blade’s blade and mounting slot size is specific to the capping head model, so confirm your head’s blade-slot dimensions before ordering.
