Professional Electrical Tool

The Gray Tools 164B-I is a 5/8 inch 12 point combination wrench rated for 1000 V insulated work. It is built for electricians and maintenance technicians who service live low-voltage panels and need verified hand protection.

Dual-Layer Safety Design

An orange outer insulation layer covers a yellow inner layer that acts as a visual wear indicator; if the yellow shows through the orange the wrench must be replaced. Each piece is individually tested to ASTM F1505 standards for dielectric strength.

Compliance Marking

The product carries California Proposition 65 warnings for chemicals linked to cancer and reproductive harm, informing buyers of regulatory obligations before use. No software or additional accessories are bundled with this hand tool.

Questions about this item

How do I verify the 1000 V insulation is intact before each use?

Check the orange outer layer and the yellow inner layer; if yellow is visible the wrench must be removed from service.

What replacement schedule applies to the 12-point insulated combination wrench?

Replace the wrench immediately once the yellow safety layer becomes visible through the orange insulation.

At what voltage does the ASTM F1505 tested insulation reach its limit?

The insulation is rated for 1000 V; exceeding that voltage voids the protection guarantee.
