Abstract
Abstract A channel-shaped gripping element and a pile seal member are secured together to provide a grippable sliding seal strip. The gripping element is secured to a flange of a fixed member, and the pile seal member slidably engages the surface of a moving member. A flexible link member is interposed between the gripping element and the pile seal member. A guard arm is provided on one of the gripping elements and pile seal members for preventing penetration of the pile by flying foreign objects.
