Featuring the same industry leading quality as all TapeTech corner finishers, the 42TT 2-1/2 in. Corner Finisher perfectly feathers both joint compound edges of internal corners in one pass. The 42TT can be used for wall-to-wall internal corners or wall-to-ceiling corners to wipe down excess mud in internal corners, embed inside corner tape on walls and ceilings, and finish inside corners of walls and ceilings.
This unit works in conjunction with the 14TT MudRunner, the 35TT or 50TT Corner Applicator or the TapeTech Compound Tubes to quickly and professionally finish internal drywall corners.
  • 2-1/2 in. size is perfect for wiping down internal corners after using the automatic taper and inside corner roller

    TapeTech Limited Five Year* Warranty

    TapeTech Tool Company (SELLER) warrants that all TapeTech tools will be free from defects in material or workmanship for a period of five (5) years* from date of purchase. SELLER'S SOLE OBLIGATION under this Warranty and, to the extent permitted by law, any warranty or condition implied by law shall be the repair or replacement of parts, without charge, which are defective in material or workmanship. At the SELLER'S sole discretion, a replacement tool may be supplied if original tool is found to be unrepairable, in which case, the original warranty term will remain in effect for the replacement tool. This warranty is void if the tool has been damaged by accident, in shipment, misuse, neglect, improper service, installation of non-TapeTech parts, unauthorized modifications or repaired by persons other than Authorized Service Centers. To make a claim under this warranty, you must return the complete tool, transportation prepaid, to TapeTech Service Center or an Authorized Warranty Repair Center.

    CUSTOMER'S RESPONSIBILITY under this Warranty begins on the date of customer purchase. Warranty is not transferable. For your convenience, keep your dated bill of sale as evidence of the purchase date. You are required to present this bill of sale to the service center to obtain warranty repair. Please include a brief statement indicating the nature of the problem. For warranty service information or a complete list of Warranty Service Centers contact the place of purchase, or contact our Customer Service Department or website for assistance:

    IN NO EVENT SHALL TAPETECH TOOL COMPANY BE LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGE, DELAY IN RENDERING OF SERVICE, OR LOSS OF USE DURING THE PERIOD IN WHICH THE TOOL IS AT THE REPAIR CENTER OR OTHERWISE AWAITING REPAIR OR PARTS. This warranty gives you special legal rights and you may also have other rights, which vary from state to state. Some states do not allow exclusion or limitations of incidental or consequential damages or limitations on how long any implied warranty may last, so the above exclusions and limitations may not apply to you.
