Now available at Metals4u.co.uk (https://www.metals4u.co.uk/Formarail-Handrail-System/1754/products.asp) Formarail® is a patent pending product which overcomes the problem of angle variations during installation and significantly reduces the number of parts needed. The Formarail® ball unit technology allows the rail to be positioned at varying gradients up to 45 degrees, making it easier and quicker to install. The ball unit is made from high quality ABS plastic, providing an excellent balance of tensile strength, impact and resistance to abrasions and extreme weather conditions.
