Introducing the New Roberts Kicker this is basically a GT2000 Kicker with a Gel Filled knee pad fitted, with the withdrawn Gel pro 5 years ago we asked our Roberts Rep to have the GT2000 fitted with the knee pad from the Gel pro kicker as every fitter we spoke to said that it was the best part of the Gel Pro kicker. So eventually the request found its way to the USA and someone there listened as result of RWS Carpet Fitters Supplies request it became reality. https://www.carpetfittersshoponline.co.uk/rws036f-roberts-gt2100-knee-kicker-the-general-1307-p.asp
