A closure strip adapted to be bonded to a substrate comprises a one-piece polymeric extrusion having a base surface essentially no wider than the profile portion of the strip and wherein a plane projected normal to and bisecting the base surface longitudinally into two parts also bisects the profile portion into two corresponding parts, a dormant but reactivatable adhesive layer adhering to and along the base surface on at least one side of the plane, so that the closure strip is adapted to be bonded to the substrate upon reactivation of the dormant adhesive.
