I agree with a previous reviewer that the dust collection system be poor . Mine keep come off and frankly , it get in the way . I beleive I have come up with a good solution . I have a porter-cable finish sander # 333v and it have a unique dust collection system . call a sand trap , it be a porus cup that work quite well , collect even the finest sanding . I purchase a spare cup for -lrb- $ $ $ -rrb- and mount it on the 1274 with a 1 inch piece of plastic tubing and a clamp . it seem to work perfectly . I 'll advise after I use it a month or so . you can buy the sand trap from Porter Cable direct by call technical service list on they web site .
