Connect your shop vac to your table saw or other equipment! Works great, especially with R4520 and R4512 saws. Is your machine equipped with a generously sized dust chute that's too wide to fit a shop vacuum hose? Our adapter fixes that! It's angled to make it easier for you to connect your hose to it—handy in situations where there's not much space to work with. And, it's curved and aerodynamic for optimum air flow into your vacuum. It's designed and manufactured here in the USA out of high quality thermoplastic using an advanced 3D printer additive manufacturing process.
