Gray Tools E028-I 1000V Insulated Wrench

The Gray Tools E028-I is a 1000 V insulated open-end wrench with a 7/8 inch hex size. It is built for electricians and maintenance technicians who work on live or potentially energised equipment up to 1000 volts. Precision machining ensures a tight, secure fit on fasteners. The tool meets ASTM F1505 standards for insulated hand tools.

Check Voltage Rating And Hex Size First

Verify that the circuits you service do not exceed the 1000 V rating marked on the wrench. Confirm the fastener size is exactly 7/8 inch so the open end engages fully without rounding corners. Inspect the dual-layer insulation before each use; the orange outer layer and yellow inner layer act as a visual safety indicator. Ensure your work procedures follow ASTM F1505 guidelines for insulated tools.

Replaces Non-Insulated Or Damaged 7/8 Inch Wrenches

This wrench replaces standard open-end wrenches that lack voltage-rated insulation for 1000 V work. It also replaces any insulated wrench whose yellow indicator layer is visible, signalling insulation compromise. The upgrade is worth it when your safety protocol requires individually tested tools compliant with ASTM F1505. It is not for tasks exceeding 1000 V or for fastener sizes other than 7/8 inch.

Questions about this item

Does the 7/8" insulated open-end wrench ship alone, or do I need to buy a storage pouch or additional jaws separately?

The wrench is sold as a single 7/8" piece. No pouch, case or extra jaws are included, so nothing else is required to use it.

I see only the 7/8" size listed — is there a different capacity or version I should choose for 1000 V work?

This model is offered only in the 7/8" hex size. Every unit is individually tested to ASTM F1505 and rated for 1000 V, so there is no alternative capacity to select.

What does the 1000 V rating mean when I am actually turning a live fastener?

The orange outer layer and yellow inner layer provide insulation up to 1000 V. The yellow layer also acts as a visual wear indicator — if it shows through, the wrench must be replaced.
