Over time the screw cover strip, also known as Herzim insert strip, on your caravan, motorhome or boat may have shrunk, cracked or faded. This screw cover strip is 13.5mm wide by 4.2mm thick and designed to fit into your existing Aluminium channel or waist rail. It is an aesthetic trim used to cover the screw heads and fixings. This product is supplied in black and is available in a range of other sizes.
To fit this product, soften the seal by placing it into warm water and then carefully pinch the seal into the channel working your way from one end to the other. Alternatively, you can use a Screw Cover Strip / Herzim Trim Fitting Tool to simplify this process. We recommend leaving the end an inch longer than required. This would allow the section to shrink back to its original length if it was unintentionally stretched during the initial fitting. Any excess can then be trimmed after a few days.
We manufacture this product from high quality PVC which is a compound suitable for a wide range of everyday and industrial applications.
