The Doorknob Extender from Maddak ABLEWARE is ideal for people with limited hand mobility, strength, dexterity, grasping capabilities, or fine motor control by turning any doorknob into a door lever that can be opened with a simple touch of the hand. It works as well as more expensive doorknob levers and it is easier to install. The5" (12.7 cm) extension handle converts a doorknob into a door lever providing extra leverage for people with limited hand function. The Extender fits over a standard doorknob and allows complete access to keyholes. A cord or string can be inserted through the unique handle slot, making doorknobs easier to access for people with limited reach. Can be installed using only a screwdriver - no special tools required.
