The Big Horn 11295 ClearFlex Hose is a premium grade PVC dust collection hose designed for both flexibility and durability. At 10 feet long with a 2½″ internal diameter, this transparent hose is reinforced with a heavy-gauge wire helix that allows it to bend into a sharp 90° arc with just a 6″ radius, ideal for tight spaces. Unlike hoses made entirely of plastic, this hose’s wire helix can be grounded to your machine and helps dissipate static build-up during operation.The transparent design lets you monitor airflow and easily detect clogs.
