15mm x 41mm - Decking Handrail Infill

15mm x 41mm Decking Handrail Infill is an essential component for creating neat, consistent, and long-lasting decking balustrades. Designed to be used with matching decking handrails, this infill helps space, align, and secure spindles correctly for a professional finish.

Decking handrail infill can be used in two ways depending on your installation method. It can be fixed directly to the spindles, which is particularly useful when using undersized spindles, before securing the infill into the groove provided in the handrail. Alternatively, the infill can be cut into spacers to allow the spindles to “float” between the rails. This second method is preferred, as it allows the spindles to naturally expand and contract with changing weather conditions, helping to reduce splitting, movement, and ongoing maintenance.

Commonly used for decking handrails, balustrades, stair rails, and raised deck areas, handrail infill helps achieve even spindle spacing while improving the overall strength and appearance of the railing system. Ordering the handrail and infill together is recommended so items can be batch-matched to ensure the best possible fit.

This decking handrail infill is suitable for both DIY deck builds and professional installations, offering a simple but effective solution for a clean, durable railing system.
