5'' (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. Fits round doorknobs from 2 1/8 - 2 3/8 (5.4 - 6 cm) diameter. Can be installed using only a screwdriver - no special tools required. Easy to clean.
