Pressure Treated Deck Spindle – 900 x 41 x 41mm allows you to build a safety railing around your decking, while also giving your decking better definition. Both ends are square-cut for easy installation. Made from redwood and white wood, this spindle has a robust 41mm thickness for added strength. It is kiln dried to help reduce the risk of splitting or twisting. It is also pressure treated, meaning you get a longer life from your deck.
