One-Handed Tri-Pin Spinner Knobs - Sure-Grip w/o Base Buyer’s Guide

The One-Handed Tri-Pin Spinner Knob by Sure-Grip is an adaptive driving aid designed to provide maximum steering wheel control for individuals with limited hand strength, grasp, or wrist function. Engineered to stabilize the hand and wrist simultaneously, this ergonomic steering device allows drivers with mobility challenges to execute smooth, precise turns using shoulder and arm motion with minimal effort.

Ergonomic Tri-Pin Design for Maximum Control

The Sure-Grip Tri-Pin Spinner Knob features a unique three-prong layout that comfortably cradles the hand and wrist. By securing the wrist between the upright pins, drivers with limited finger dexterity or grip strength can safely steer and maneuver the vehicle using larger muscle groups in their arm and shoulder.

Sure-Grip Adaptive Driving Aid

Built specifically for adaptive driving, this spinner knob assists drivers with spinal cord injuries, quadriparesis, or reduced hand function. The stabilizing design keeps the driver's hand firmly positioned, making everyday driving, tight turns, and parking maneuvers noticeably safer and less strenuous.

Padded Pins for Extended Driving Comfort

Each pin on the Tri-Pin Spinner Knob is covered with soft padding designed to reduce pressure points against the skin and wrist during prolonged use. This thoughtful cushioning helps prevent discomfort and skin irritation, ensuring a comfortable driving experience even on long road trips.

Quick-Release Mounting Mechanism

Featuring a convenient quick-release button, the Tri-Pin Knob can be effortlessly mounted or removed from the steering wheel attachment base in seconds. This allows non-disabled drivers or secondary users to easily share the vehicle without the spinner knob getting in their way.

Non-Marring Steering Wheel Protection

When paired with the Sure-Grip base unit, the attachment mechanism uses a protective clamshell design that grips the steering wheel securely. It leaves no permanent scuffs, marks, or indentations on the factory wheel finish, preserving your vehicle's interior appearance.

Smooth One-Handed Steering Capability

The internal bearing mechanism allows the Tri-Pin to spin freely and fluidly, enabling 360-degree rotation of the steering wheel with a single hand. This reliable movement lets drivers keep one hand dedicated to vehicle hand controls like gas and brake levers without losing steering authority.

Durable and Heavy-Duty Construction

Constructed from high-quality, durable materials, the Sure-Grip Tri-Pin is engineered to withstand daily driver use while maintaining smooth operation. Its robust frame provides reliable performance and long-term stability across various weather conditions and driving environments.

Versatile Vehicle Compatibility

Designed for broad utility, this spinner knob works seamlessly across most cars, trucks, and vans adapted for drivers with disabilities. It serves as a direct replacement or alternate grip option for users who already have the Sure-Grip base system installed on their steering wheel.
