Clamp Meter Recall - Other

Klein Tools is issuing a voluntary product recall on four products 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.

Why Is There A Recall?

The CL110, CL210 and CL310 and CL110KIT are being recalled due to a fastener that can work itself loose over time, potentially leading to a false reading when measuring voltage. This issue could indicate a reading of zero voltage on energized systems resulting in the operator falsely believing the electrical power is off, posing shock, electrocution and burn hazards. This recall involves The CL110, CL210 and CL310 and CL110KIT Digital Clamp Meters with date codes:
