Abstract
A sealing, trimming or finishing strip has a metal carrier advantageously made up of U-shaped side-by-side metal elements interconnected by integral connecting links. The carrier is completely embedded in flexible material, such as rubber or plastics material, which defines inner gripping and sealing lips. A sealing portion is also provided. Substantially all of the material on the inside of the carrier (including the material of the lips) is sufficiently transparent or translucent to enable the carrier, or at least the connecting links thereof, to be visible through it. This facilitates cutting of the strip into lengths, because it enables the cutter to be located so as to cut through the connecting links of the carrier, rather than through the U-shaped elements thereof. The channel-shaped material externally of the carrier is visually opaque.
