1000 V Insulated Combination Wrench

The Gray Tools 167B-I is a 7/8 inch combination wrench insulated for live electrical work up to 1000 V. It is built for electricians and maintenance technicians who must service energised panels or equipment. The 12 point drive engages fasteners from multiple angles in confined spaces.

Dual-Layer Insulation and ASTM F1505 Testing

An orange outer insulation layer covers a yellow inner layer that acts as a visual wear indicator; damage to the orange layer reveals the yellow beneath. Each wrench is individually tested to ASTM F1505 standards before shipment. Users must inspect the insulation before every use and retire the tool if the yellow layer becomes visible.

7/8 Inch Hex Limitation and Proposition 65 Notice

The fixed 7/8 inch hex size limits the wrench to a single fastener dimension, so additional sizes are required for broader tasks. The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm. It is not suited for applications requiring non-insulated tools or different hex dimensions.
