Insulated Combination Wrench 11/32

This Gray Tools combination wrench provides a 12-point opening sized at 11/32 inch for fastener work. It carries a 1000 V insulation rating and is individually tested to ASTM F1505 standards. The tool is intended for electricians and maintenance technicians who work on or near live electrical equipment.

Two-Layer Visual Safety Indicator

The wrench features an orange top insulation layer over a yellow inner layer that acts as a visual wear indicator. Damage to the orange layer reveals the yellow layer beneath, signalling that the insulation integrity may be compromised. This replaces single-layer insulated tools where wear is harder to detect without dielectric testing.

1000 V Rating Practical Limits

The 1000 V rating applies only while the insulation remains undamaged and the tool is used within its designated voltage class. It does not protect against voltages exceeding this level or against current paths created by damaged insulation. California Proposition 65 warnings apply for chemical exposure.

Questions about this item

What is the 11/32" hex size of this 159B-I combination wrench?

The wrench is machined to fit an 11/32 inch fastener, providing a precise 12-point grip on that specific dimension.

How do I correctly install this insulated wrench for 1000 V protection?

Inspect both the orange outer and yellow inner insulation layers before every use; any yellow showing means the dielectric barrier is compromised and the wrench must be replaced.

When should I replace this 159B-I wrench based on its insulation condition?

Replace it immediately once the yellow safety layer becomes visible through the orange coating, as the 1000 V rating to ASTM F1505 is no longer guaranteed.
