Device Details


Some people with limited grip strength/hand function have difficulty opening the gas cap on their vehicle. There are several commercial and DIY options available for opening vehicle gas caps, but most focus on grip strength issues, with limited options available for users with limited hand function.


To use, the + shaped end of the gas cap opener over the gas cap on the car. The handle on the opener can then be turned to either tighten or loosen the cap, as normal.

If this device does not function with the gas cap on your vehicle, please get in touch with us so we can make changes to the design to make it compatible with more vehicles.
