The TapeTech corner finisher is used to perfectly smooth both edges of the inside corner joint compound in one pass. 

The corner finishers can be used for internal wall-to-wall corners or wall-to-ceiling corners. Corner finishers, also known as angle finishers, attach to a corner applicator (CA07TT or CA08TT) or the MudRunner® 14TT to quickly and professionally finish internal drywall corners. The 40TT 50mm Corner Finisher is often used with the HF fiberglass handle as part of the taping process to embed tape in the corners and remove excess joint compound after the 15TTE corner roller. Use with FHTT or XHTT handles - Not included.

• Removes excess compound from inside corners
