Additional removable Petri+Lehr steering aids for active drivers

Professional driving aids that make steering easier

Petri+Lehr Lenkraddrehknopf

Steering wheel turning knob

The Petri+Lehr steering wheel turning knob (LDK) is removable and therefore meets TÜV (German Technical Inspection Agency) requirements. The LDK provides comfortable hold in your hand and fits perfectly into your vehicle's interior. The bracket on the steering wheel is padded with a soft foam and has pleasant surface characteristics. A bracket beneath the steering wheel is available for some Mercedes-Benz models. Wherever it is installed, the LDK simply lies comfortably in your hand.

Petri+lehr Tetragabel

Tetra fork

The Petri+Lehr tetra fork always guarantees safe steering without re-gripping.
Like the steering wheel turning knob, the fork, which can be removed at any time, is mounted on the steering wheel with a plug-in spindle and clamp bracket.
Particularly suitable on loss of finger function (e.g. tetraplegia). Residual strength in the wrist must be present.

Petri+lehr Zweizack

Two-prong

Thanks to adjustable prongs and individual adaptation to the hand, this two-prong guarantees even safer steering without re-gripping. Also mounted on the steering wheel with a plug-in spindle and clamp bracket, the two-prong can be removed at any time.
Particularly suitable on loss of finger function (e.g. tetraplegia). Residual strength in the wrist must be present.

Petri+Lehr Dreizack

Thanks to slotted brackets, all three prongs are adjustable and can be individually adapted to secure the hand and wrist in position. The three-prong is mounted on the steering wheel with a plug-in spindle and clamp bracket, and can be removed at any time.

Can be used without residual strength in the wrist.
