Gripnail's Spindle Anchors easily install any type of insulation up to 3.5" thick. Spindle Anchors are perfect for installing fiberglass insulation, rubber insulation blankets or polystyrene boards. Spindle Anchors can attach to air ducts, metal buildings, concrete foundations - even to the underside of wooden roofs. Spindle Anchors are perforated to allow adhesive to lock the fastener in place.
