16 mm 1000 V Insulated Open-End Wrench

This 16 mm open-end wrench is individually insulated and tested to ASTM F1505 for live-line work up to 1000 V. It suits electricians and maintenance technicians who need a single insulated spanner for panel and terminal tasks. The orange top layer and yellow indicator layer give a clear visual check on insulation integrity.

Check voltage rating and jaw size before ordering

Verify that the 1000 V rating matches the maximum system voltage you will encounter and that the 16 mm hex size fits the fasteners on your equipment. Confirm the ASTM F1505 marking is required by your site safety procedure. Ensure you have space for an open-end profile rather than a ring or socket drive.

Two-colour insulation acts as wear indicator

The orange outer layer and yellow inner layer let you spot damage at a glance; if yellow shows through, the wrench must be removed from service. No case, pouch or additional test certificate is mentioned in the supplied data. The Proposition 65 notice applies to chemical content, not to electrical performance.
