The RIDGID 1/4 Sheet Sander features a powerful 2.4 Amp and easy-load system to quickly clamp paper tightly and securely. For added convenience, the onboard vacuum adaptor fits standard 1-1/4 in. or 2-1/2 in. hoses. And, for a cleaner, virtually dust-free work environment, the AIRGUARD on-board active dust collection system collects up to 90% of dust.
