Attachment strips that can be withdrawn from an enclosure, each comprising a flexible backing layer, a field of hooks along and projecting from one of its surfaces; and a first layer of pressure sensitive adhesive along one of its surfaces. The strips can be releasably adhered to each other by their layers of adhesive to form a stack in which first and second ends of successive strips are adjacent. The strips have un-adhered portions or their adhesion to adjacent strips is controlled so that when the stack of strips is positioned in the chamber with the first end portion of the uppermost strip in the stack projecting through the slot and resting against the adjacent abutment surface, and tension is applied to that uppermost strip to pull it through the slot, that tension will cause successive portions of the uppermost strip to peel from the first underlying strip in the stack and will cause separation of the first end portion of the first underlying strip from the second underlying strip, and movement of the first end portion of the first underlying strip through the slot with the second end portion of said uppermost strip to leave, after the uppermost strip is fully peeled from th…
