Robooter Square Joystick Knob – High-Density OEM Replacement

Regain total command of your mobility with the Robooter Square Joystick Knob. Whether you’ve lost your original knob or are looking for a more ergonomic upgrade, this high-density OEM replacement is engineered specifically for the Robooter X40 (and also fits E40/E60 models). Designed for enhanced durability and precision, this square-profile grip ensures every movement of your electric wheelchair is smooth, secure, and comfortable.

Ergonomic Control & High-Density Durability

The unique square geometry of this knob is designed to offer a more intuitive feel than standard round grips.

• Dense, Non-Slip Material: Crafted from a specialized high-density polymer that provides a tactile, "grippy" feel, ensuring your hand stays securely in place even during long journeys or in damp conditions.

• Enhanced Tactile Feedback: The square edges provide clear directional reference points, making it easier to maneuver with precision in tight indoor spaces or crowded areas.

• Comfort-First Design: The contoured top is shaped to provide a comfortable hold, reducing hand fatigue for users who rely on their joystick for extended periods.

Genuine OEM Quality

This is a factory-spec replacement designed to integrate perfectly with the Robooter control system.

• Universal Robooter Compatibility: While optimized for the X40, this knob is a perfect fit for the E40 and E60 models, making it a versatile spare part for the entire E-Series and X-Series lineup.

• Built to Last: The high-density construction is impact-resistant and UV-stabilized, preventing the material from becoming sticky or brittle over time.

• Simple Press-Fit Installation: No tools required. The knob is designed to slide firmly onto the controller shaft for a secure, wiggle-free fit in seconds.
