Rockler's industry-first Anti-Static Dust Hose is impregnated with ''carbon black,'' virtually eliminating the static build-up that can lead to shocks. It is rugged, yet flexible-a true pleasure to use. To understand static build-up in a plastic dust hose, think of a tubular plastic playground slide. The dust and chips flowing through the hose can create a large amount of friction and static charge. While some dust collection systems remedy the problem with a grounding wire, this hose prevents the problem at the source-the hose itself. This flexible and durable hose has a 4'' inside diameter and is 10 feet long. It is made from a durable plastic helix with carbon black added to dissipate static build-up.Note: For use with left hand threading accessories. This product will not work with Right Hand Thread Bridge Hose Clamps (#26177) or Clamped Quick Disconnect Fitting (#37789) .
I thought it would be bad quality, because it costs just 44.99 . But I surprised, because amazingly it's very good product, maybe best Rockler Dust RightA (R) 4'' Anti-Static Dust Hose!
