Frequently Asked Questions
Will these fit my HELIX 7?
No. The HELIX 7 (and HELIX 5) use a physically smaller mounting bracket and smaller diameter screws. These knobs are too large for those units. You need the "Compact" Helix knob kit.
Do these come with the rubber washers?
In most current kits, the friction washer is integrated or supplied as part of the knob assembly to prevent the unit from slipping. (Note: If your bracket requires separate ratchet teeth, check your specific model, but these are the standard threaded knobs).
My knobs keep vibrating loose. Will new ones fix this?
Often, yes. Over time, the threads on old knobs can stretch or the plastic grip can separate from the metal bolt, making it hard to tighten them fully. A fresh set of knobs allows you to apply the necessary torque to keep the unit stable in rough water.
