This Everlasto Nylon Plait Sash Cord is made from strong plaited nylon fibres making it one of our strongest sash cords. These plaited nylon cords are ideal for where extra strength is required. As they are synthetic these sash cords are weatherproof and will resist rot, mildew and mould. Ideal for use primarily with sash windows but also can be used as a nylon washing line, pulley line, with clothes airers or as a strong general purpose rope. Made in the UK by James Lever and Sons.
