Car Steering Wheel Opening Aid Grip Tool Easy Access Helper Device for Vehicle

Reversing a trailer into a tight yard means winding lock to lock while looking over your shoulder, and one hand on a bare rim runs out of reach halfway through. This is a spinner knob: a rotating grip that clamps to the steering wheel rim so a single hand can take the wheel right around without letting go.

Rubber grip on a nylon body

The grip turns on its own axis as the wheel goes round, which is the entire point — your hand stays in one position on the knob while the rim rotates underneath it. Rubber over the outer surface gives something to hold with a sweaty or gloved hand, and the nylon body carries the clamp. At 93 mm tall with a 52 mm grip diameter it sits in a closed fist, and the 64 mm base spreads the clamping load along a length of rim rather than concentrating it on one spot. Two screws and an Allen key are supplied for fitting.

Worth knowing before you fit one

A spinner knob changes how the wheel is held. It encourages one-handed steering, it puts a fixed object on the rim that the other hand can catch on, and it sits in an area that matters in a crash. Requirements for steering aids and for anything fitted to a steering wheel vary between Australian states and territories, and can differ again depending on how the vehicle is used and registered. Check the rules that apply to your vehicle before fitting. That check sits with you, and nothing here states what the law requires.

Key features

• Free-turning grip: rotates as the wheel turns, so one hand can carry it through full lock.
• Rubber outer surface: textured for hold with wet or gloved hands.
• Nylon body: keeps weight down on a part that hangs off the rim.
• Clamp fitting: two screws and the Allen key are in the pack, so no separate tools are needed.
• Rim thickness limit: the supplier states it suits steering wheels up to 1-1/4 inches thick — measure your rim before ordering.
