This is the all new Air Stretcher that has evolved from the original "Air Kicker" knee kicker replacement tool. As with the Air Kicker the AS-1000 is used primarily as a placement tool. While the AS-1000 can be used to stretch closets and very short spans of carpet it is recommended to use a power stretcher to achieve CRI specifications for stretch on length and width (1 to 1.5 % stretch depending on manufacturer recommendation).
