Drywall Finishing Movie Transcript
The extension rim on the Dryerbox protrudes 7/8's of an inch from the nailing flange offering a built in corner bead. A roto zip spiral saw type tool will cut out the opening just like any other receptacle creating a small crevice that gets caulked by the painter when he caulks the baseboard. This built in corner bead rim protects the drywall from damage and provide enough of a reveal for the trim carpenter to butt his baseboard to.
