For rod builders and rod repairs. We sell this tube in a wide variety of colours and patterns. The initial diameter is 30mm and it will shrink to 18mm so it will shrink to the size of most beach fishing butt diameters. When shrunk it provides a good finish and a comfortable grip that stops your hands slipping on the butt, especially when they are wet and cold. It also wipes down easily when it needs to be cleaned. Coming in 1.6m length, the tube can be cut to the require length, slid on, and then steamed or placed in boiling water to shrink to the size of the butt.
