SKU CH-DGHB-7WT6T

1000 V insulated open-end wrench with 3/8" hex, dual-layer orange and yellow insulation and ASTM F1505 testing

  • Insulated to 1000 V for live electrical work
  • Dual-colour insulation layers show damage at a glance
  • Tested to ASTM F1505 for verified protection
  • Precision-machined 3/8" jaw gives a secure fit
  • Proposition 65 listed for chemical safety awareness

3/8″ Insulated Open-End Wrench

This 3/8″ open-end wrench is individually insulated and tested to ASTM F1505 for live-line protection up to 1000 V. Electricians and maintenance technicians working on energised panels or hybrid-vehicle systems will find the dual-layer coating a reliable safeguard during voltage exposure. The precision-machined jaw delivers a secure fit on fasteners without rounding corners.

Verify Jaw Size and Voltage Rating

Confirm that 3/8″ matches the fastener you intend to turn, as no other sizes are included with this model. Inspect the orange outer layer and yellow inner indicator before each use; damage to either layer means the tool no longer meets its 1000 V rating. The product carries California Proposition 65 warnings for chemicals linked to cancer and reproductive harm, so handle with appropriate hygiene.

Replaces Worn or Non-Insulated Wrenches

Swap this in when an existing insulated wrench shows cracked or abraded coating, or when a standard chrome wrench is the only option currently in the kit. The jump is worth it whenever work procedures require verified 1000 V insulation rather than makeshift tape or sleeves. For tasks needing a box end, ratcheting action or a different hex size, a separate tool is required.

Questions about this item

What comes with the 3/8" insulated open-end wrench and do I need anything else?

The wrench is supplied as a single piece, individually insulated and tested to ASTM F1505. No additional components are required for its rated use.

How do I choose the right version of this 1000 V insulated wrench?

This model is offered in a 3/8" hex size with dual-layer orange-over-yellow insulation. Select it when that exact opening matches the fastener you are working on.

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

It certifies protection up to 1000 volts AC/DC when the insulation is intact; the yellow inner layer acts as a visual safety indicator if the orange outer layer is damaged.
