Good to know

This trunking is not halogen-free but offers flame-retardant and self-extinguishing properties, making it suitable for most indoor applications. It can be cut to length with standard PVC saws or shears, and matching accessories such as corners, end caps, and junction pieces are available separately to complete the installation. For best results, fix the base at intervals of approximately 500 mm using suitable screws and wall plugs.
