NCVT1 Recall

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.

These affected products are sold in the following SKU numbers:

NCVT1 69149
