    Abstract: This invention is a Telescoping Handle Doorstop Wedge, the light-weight high-quality aluminum handle of which can be closed-down or extended-up, stopping at any length between 9 inches and 38 inches. When extended, the Telescoping Handle Doorstop Wedge can be lengthened and custom adjusted to any person's comfortable/practical operating height, thus making it easy for the permanently-attached non-marking, non-skid, wide-footprint, oversized rubber doorstop wedge to be effortlessly inserted into or retracted from the space between the bottom edge of a hinged door and the floor below. The invention's non-stoop, no-muscle-strain benefits are obvious for persons such as those who are disabled, infirmed and elderly, or for other persons who cannot or simply do not prefer to bend or stoop so as to painlessly, effectively and accurately insert or release a doorstop wedge.
