The TapeTech Corner Roller quickly and accurately embeds the tape firmly into the internal corners of the drywall. Use the corner roller immediately after applying joint tape to the internal corner with the automatic taper. The corner roller forces excess joint compound out from behind the tape in preparation for the corner finisher. The TapeTech Corner Roller features stainless steel rollers for crisp edges and long life. Use with the FHTT Fiberglass Handle or the XHTT Extension Handle – not included. NOTICE: A new stud design was implemented in April 2012. For information regarding model 15TTE manufactured prior to April 2012, please see the Discontinued Products page of the website. The schematic can also be viewed in the Learning Center.
