Tapered Seal. Details com SEAL104 Designed to suit an uneven gap under the door. SEAL104 is a tapered shower seal that is designed for use on the bottom horizontal section of a bath shower screen or shower door. The seal tapers to suit an uneven gap between the bottom of the glass and top of the bath or tray. This seal can be pushed into place over any glass that measures between 4mm and 6mm and will not need any type of adhesive to hold it in place. This shower seal has a 35mm tall soft fin on the bottom of the U section which tapers down to a 25mm tall soft fin on the other end. Once pressed against a flat surface (e.g. your shower tray or bath edge) this seal will compress and create a watertight seal. Our tapered seals come in a number of different sizes to accommodate any size gap. In most cases we recommend using a seal with a fin between 2-5mm bigger than the gap you need to seal.
