A useful component in making slides is the elbow tube. The 90-degree elbow tube is ideal when one is constructing a spiral slide as it has a nice curve to it. The design of this tube has a bell on one end that makes the connection from tube to tube secure. This elbow tube is of immense utility value when crawl tunnel construction is being undertaken. This elbow tube can be used for making slides for children between 2 to 12 years of age. The diameters available are 24-inches and 30-inches and you can choose one as per preference. Color options are also available.
