Gray Tools E032-I 1000V Insulated Open End Wrench 1

SKU CH-CZFY-B9MN8

One-inch insulated open-end wrench tested to ASTM F1505 for 1000 V protection with dual-layer safety indication

  • Insulated to 1000 V for live-circuit safety
  • Dual orange-and-yellow layers show insulation damage at a glance
  • Precision-machined 1" jaw gives a secure, slip-resistant fit
  • Tested to ASTM F1505 for verified dielectric protection
  • Individually insulated and tested for reliable performance

1000 V Insulated Open-End Wrench

This 1 inch open-end wrench carries a 1000 V insulation rating for work on live electrical equipment. Two insulation layers provide protection, with the outer orange layer and an inner yellow layer that acts as a visual wear indicator. Each wrench is individually tested to ASTM F1505 standards.

Electrical technicians needing certified live-line

Suited for electricians and maintenance crews who require verified 1000 V insulation on a single fixed size. Not for buyers who need a range of sizes, adjustable jaws, ratcheting action or non-insulated wrenches for general mechanical tasks.

1 inch hex opening

The wrench fits a 1 inch hex fastener and no other size. Precision machining ensures a secure fit on that specific dimension. Confirm the fastener size before purchase because the tool cannot accommodate smaller or larger heads.

Questions about this item

What does the 1000 V rating mean when I am using the wrench on live equipment?

The wrench is individually insulated and tested to ASTM F1505, so it protects the user up to 1000 V during electrical work.

What standard governs the insulation and how does it limit the tool's use?

ASTM F1505 certifies the double-layer insulation; the orange outer and yellow inner layers show damage visually and cap the rating at 1000 V.

What clearance does the 1-inch open end need to fit on a fastener?

The precision-machined 1-inch hex opening requires enough space to slide over the bolt head or nut without obstruction.
