Description
Connects standard 2-1/2 inch shop vacuum lines to smaller 1-1/2 inch power tool ports for cleaner workspace operation. The Magnum W101121 (KMS SKU: DC-W101121) bridges the gap between large-volume collection and small-port tools like detail sanders or biscuit joiners. The stepped internal design ensures high air velocity is maintained through the transition.
- Concentric Reduction – Provides a smooth internal taper to minimize air turbulence and prevent clogging.
- Durable ABS Plastic – Built to withstand the abrasive nature of sawdust and wood chips at high speeds.
- Friction Fit Design – Features slightly tapered ends to ensure a snug, tool-free connection to most hoses.

Frequently Asked Questions
Q: Will this fit my handheld orbital sander? A: Most sanders use a 1-1/4″ or 1-1/2″ port; check your tool’s manual to ensure it matches the 1-1/2″ OD of this reducer.
Q: Can I use a hose clamp on this? A: Yes, if the friction fit is too loose for your specific hose, a standard worm-gear clamp can be used.
