A 10 metre length of transparent, flexible dust extractor hose with a 100mm (4 inch) internal diameter. This is a common size that fits most workshop extractors. The hose is made from PU (Polyurethane), which is five times stronger than traditional PVC, and its transparency allows for easy identification and clearing of blockages. It features a right-handed, copper-coated, steel wire helix for strength and shape retention, which can also be used for grounding if static build-up is a concern. Note: The hose is compressed for shipping and will measure shorter than its actual length when unpacked and laid flat due to contraction. It needs to be extended to its full length before confirming the measurement.
