Klein Tools is issuing a voluntary product recall on the NCVT-1 in our Test and Measurement Line due to a potential safety hazard. We are working together with the United States Consumer Product Safety Commission and Health Canada to recall these products and replace them promptly.

These affected products are sold in the following SKU numbers:


| MPZ00001 | MPZ200052R | 69149 | 80018 | 80023 |

This recall involves Klein Tools Non-Contact Voltage Tester with model numbers NCVT1 bearing date codes ending H7. The product was also sold in variations and kits listed above, all bearing date codes ending in H7.

Why is There A Recall?

It has recently come to our attention that one of our products, the NCVT-1 NONCONTACT VOLTAGE TESTER, has a potential safety issue that Klein Tools would like to rectify. The on/off button of the NCVT-1 is intended to be pressed down and then released. If the button remains depressed during the power on or power off cycle, the tip of the tool remains illuminated in green, indicating the tool is “ready to detect voltage,” when it is not.

Other items in kits where NCVT1 was included, are not being recalled, specifically.

These items should not be sent back for replacement and should be retained by customers.

  • MM300 (Digital Multimeter), RT105 (Receptacle Tester) in Kit 69149
  • 11055 Wire Stripper, 32500 Multi Bit SD, RT210 (GFCI Receptacle Tester) in Kit 80018
